There is no doubt that ‘Umar ibn al Khattab is amongst the most renowned of the Sahabah and without a doubt whoever will name his child ‘‘Umar’ intends thereby to name him after ‘Umar ibn al Khattab.
He is ‘Umar, the son of Khattab, the son of Nufayl, the son of ‘Abdul Uzza, the son of Riyah, the son of ‘Abdullah, the son of Qurt, the son of Zarah, the son of ‘Adi, the son of Ka’b.
His genealogy meets with that of the Prophet salla Llahu ‘alayhi wa sallam at Ka’b.
His mother is Hantamah, the daughter of Hashim, the son of Mughirah, the son of ‘Abdullah, the son of ‘Umar, the son of Makhzum, the son of Yakzah, the son of Murrah.
His genealogy meets with that of the Prophet salla Llahu ‘alayhi wa sallam from his mother’s side at Murrah.
The Banu ‘Adi, according to what Ibn al Kalbi has reported, were amongst the most generous of people, holding a distinguished position during the Days of Ignorance. Ibn al Kalbi says:
The Quraysh would seek council (in their disputes) from his grandfather, Nufayl ibn ‘Abdul ‘Uzza.
As for the status of ‘Umar ibn al Khattab radiya Llahu ‘anhu in Islam; the books of Hadith contain sufficient mention of his merits and virtues. Merely examining the conquests and spread of Islam during his Caliphate—especially in the lands of the Romans and Persians—is sufficient testimony to his noble status.
Amir al Mu’minin ‘Ali radiya Llahu ‘anhu named one of his sons after ‘Umar. His mother is Umm Habib al Sahba’ al Taghlabiyyah, who was amongst the captives from the apostasy wars during the caliphate of Abu Bakr radiya Llahu ‘anhu.
Ibn ‘Inabah said in ‘Umdat al Talib:
The progeny of Amir al Mu’minin continued through five of his sons: Hassan, Hussain, Muhammad ibn al Hanafiyyah, ‘Abbas al Shahid, and ‘Umar al Atraf.
Ibn Qutaybah stated in al Ma’arif:
‘Umar and Ruqayyah: Their mother is Taghlabiyyah. Khalid ibn Walid captured her as prisoner of war and ‘Ali then purchased her.
Mus’ab al Zubairi said in Nasab Quraysh:
Umar ibn ‘Ali and Ruqayyah were twins, their mother is al Sahba’.
He is a well-known personality and his biography is contained in a number of books. There is a famous story reported about him seeking to be appointed in charge of distributing the charities of Sayyidina ‘Ali radiya Llahu ‘anhu. His biography can be read in:
The famed genealogist Ibn Tiqtaqa (d. 709 AH.) establishes another child from ‘Ali by the name ‘Umar (al Asghar). It may be an error from his side, and he meant to write ‘Umar al Atraf. However, it is possible that there was another child with that name, especially since his (al Asghar’s) mother’s name is recorded as Umm al Banin al Kilabiyyah and not al Sahba’, who is the mother of ‘Umar al Atraf. So it is possible that ‘Ali radiya Llahu ‘anhu had two children with the same name ‘Umar, one younger and the other older—who was al Atraf.
The words of Ibn Tiqtaqa are:
The names of those children of Amir al Mu’minin who left behind no progeny, and they are fifteen sons: ‘Awn, whose mother is Asma’ bint ‘Umays al Khath’amiyyahدرج, Muhammad, whose mother is Asma’ bint ‘Umays al Khath’amiyyahدرج, ‘Uthman, whose mother was Umm al Banin, who was martyred at Karbala’, Yahya, whose mother is Asma’ bint ‘Umays al Khath’amiyyahدرج, ‘Umar al Asghar, whose mother was Umm al Banin, ‘Abbas al Asghar, whose mother was a Umm Waladدرج, ‘Ubaidullah, whose mother was Layla al Daramiyyah, who was killed alongside Mus’ab ibn Zubairدرج, Salih, whose mother was an Umm Walad, Abu Bakr, whose mother was Layla al Daramiyyahدرج, ‘Abdul Rahman, whose mother was Umamah bint Abi al ‘As ibn al Rabi’—the daughter of Zainab bint Rasulillahدرج, Muhammad, whose mother was Umamah bint Abi al ‘Asدرج, Jafar, whose mother was al Hanafiyyahدرج, in other words he passed away and left no offspring, Jafar, whose mother was Umm al Banin, who was killed at Karbala’, ‘Abdullah, whose mother was Umm al Banin, who was killed at Karbala’, ‘Abdullah, whose mother is Asma’ bint ‘Umays al Khath’amiyyahدرج.
There are a number of inaccuracies in what Ibn Tiqtaqa has stated, amongst is what the researcher Mahdi al Raja’i has indicated that he has confused ‘Umar al Asghar with ‘Umar al Atraf.
Al Baladhuri states in Ansab al Ashraf:
‘Umar ibn al Khattab gave a slave by the name of Muriq as a gift to ‘Umar ibn ‘Ali, who had been named after him.
The genealogist Abu al Hassan al ‘Umari writes:
‘Umar, whose agnomen was Abu al Qasim—Ibn Khada’ says that his agnomen was actually Abu al Hafs—and Ruqayyah; their mother is al Sahba’ bint Rabi’ah al Taghlabiyyah.
Sayyidina Hassan ibn ‘Ali radiya Llahu ‘anhu also named his son Umar. His mother was an Umma Walad and he was martyred alongside his uncle, Sayyidina Hussain radiya Llahu ‘anhu, in Karbala’.
Al Yaqubi writes:
Hassan had eight sons: Hassan, Zaid…’Umar, Qasim, Abu Bakr, ‘Abdul Rahman from a number of Umm Walads, Talhah, ‘Abdullah…
Some have erred concerning his name being ‘Umar, and assumed it was ‘Amr. The correct opinion is what we have stated, that his name was ‘Umar. The one to claim that it was ‘Amr was al Mufid in Kitab al Irshad (2/20) and al Irbili in Kashf al Ghummah (2/184). Also amongst those who erred in this regard was Mus’ab al Zubairi in Nasab Quraysh where he said:
Similarly Ibn Tabataba Yahya ibn Muhammad ibn Qasim al Hussaini (d. 478 A.H) made the same error when mentioning the children of Hassan ibn ‘Ali radiya Llahu ‘anhu:
The remaining sons: Talhah whose mother was Umm Ishaq bint Talhah ibn ‘Ubaidullah al Taymi, ‘Amr, Hussain who bore a daughter named Umm Salamah… ‘Abdul Rahman, ‘Abdullah, Muhammad, Jafar, Hamzah; all of whom were either martyred at Karbala’ or had no children.
Also amongst those who erred in his name was al Tustari in Tawarikh al Nabi wa al Al (pg. 12).
The reader may be wondering as to the reason why we claim the correct name is ‘Umar and not ‘Amr?
The answer to this is:
Ibn ‘Inabah, one of the famed genealogists—who studied under Ibn Mu’ayyah (genealogist)—has mentioned this in his book wherein he has relied upon the pioneers of this science such as Abu Nasr al Bukhari, the author of Sirr al Silsilat al ‘Alawiyyah; Sheikh al Sharaf al ‘Ubaidali, and many others.
Ibn ‘Inabah has reported from Sheikh al Sharaf al ‘Ubaidali that among the children of Hassan radiya Llahu ‘anhu were two sons: Abu Bakr and ‘Umar. He then reported from Abu Nasr al Bukhari, saying:
Abu Nasr al Bukhari said, “Hassan ibn ‘Ali had 13 sons and 6 daughters. His progeny continued from 4: Zaid, Hassan Hussain al Athram, and ‘Umar. Hussain al Athram and ‘Umar did not have lengthy lifespans.”
In al Ma’arif too it has been indicated that his name was ‘Umar:
Hassan had the following children: Hassan, whose mother was Khawlah bint Manur ibn Zaban al Fazariyyah; Zaid and Umm Hassan, whose mother was Bint ‘Uqbah ibn Mas’ud al Badri; ‘Umar, whose mother was from the Banu Thaqif…
The author of Mukhtasar Dhakha’ir al ‘Uqba also mentioned:
Hassan had 11 sons and daughters. They are: ‘Abdullah, Qasim, Hassan, Zaid, ‘Umar…
‘Abbas al Qummi said:
Amongst the genealogists who mentioned ‘Umar to be amongst the children of Hassan is Dhamin ibn Shadqam al Hussaini (d. 1090 A.H) in his book Tuhfat al Azhar wa Zilal al Anhar fi Nasab Abna al A’immah al Athar. Kamil Sulaiman al Jabouri examined this book and drew up family trees wherein he mentioned ‘Umar ibn Hassan, and that he passed away in Abwa while donning his Ihram for Hajj. He was with his uncle, Hussain radiya Llahu ‘anhu, when he intended to set out to Kufah.
The martyr of Karbala’, Imam Hussain, also named his son after Umar ibn al Khattab.
Al Tustari said:
Abu Hanifah al Dinawari and Ibn A’tham al Kufi have proven him to have a son named ‘Umar. The first (Abu Hanifah al Dinawari) said (after discussing the incident of Karbala’ and the number of those martyred), “None remained of his Ahlul Bayt except his two sons; ‘Ali al Asghar—who was ill, and ‘Umar who was four years old at the time. Yazid said to ‘Umar ibn Hussain one day, “Will you wrestle with my son,” pointing to Khalid ibn Yazid who was a similar age to him. ‘Umar said, “Rather give me a sword and give him a sword and then let us fight! Then we will see which of us is more endearing.” Yazid grabbed hold of his son and hugged him. Yazid then said, “The apple does not fall far from the tree! Will a snake produce not but a snake!” ‘Umar was seven years old at the time.
The son of the Zayn al ‘Abidin, considered to be the fourth infallible Imam by the Shia, was named ‘Umar. His mother was an Umm Walad. His title was al Ashraf as the son of ‘Ali ibn Abi Talib radiya Llahu ‘anhu was titled ‘Umar al Atraf.
Ni’matullah al Jaza’iri says:
As for his ‘alayh al Salam children they are 15 sons: Muhammad al Baqir ‘alayh al Salam, whose mother was Umm ‘Abdullah Fatimah bint Hassan ibn ‘Ali ibn Abi Talib ‘alayh al Salam; Abu al Hassan Zaid and ‘Umar, whose mother was an Umm Walad.
Ibn ‘Inabah about ‘Umar al Ashraf:
He was called Ashraf in relation to his father’s paternal uncle, ‘Umar al Atraf, (who was called al Atraf) because his virtue was through one parent, namely his father Amir al Mu’minin ‘Ali ibn Abi Talib radiya Llahu ‘anhu.
Al Mufid said:
‘Umar ibn ‘Ali ibn Hussain was an esteemed personality. He took responsibility of distributing the charities of the Prophet salla Llahu ‘alayhi wa sallam and the charities of Amir al Mu’minin ‘alayh al Salam. He was pious and extremely generous.
Ibn al Tiqtaqa said:
As for Abu Hafs ‘Umar al Ashraf… He was one of the scholars of the Banu Hashim, virtuous and generous.
Abu al Hassan al ‘Umari said:
‘Umar al Ashraf ibn ‘Ali ibn Hussain ibn ‘Ali ibn Abi Talib ‘alayh al Salam was born, and he was given the agnomen Abu Hafs. He lived until the age of 65.
I say: Ponder! ‘Umar al Atraf had the agnomen Abu Hafs, as mentioned by Ibn Khada’, as well as ‘Umar al Ashraf. Al Tustari in Qamus al Rijal lists a number of Muhaddithin, Fuqaha’ and authors from the progeny of the Imams who had the name ‘Umar as well as the agnomen Abu Hafs.
The great grandson of the fourth Imam Zayn al ‘Abidin was also given the name ‘Umar.
Ibn ‘Inabah says:
As for ‘Umar al Shajari ibn ‘Ali ibn ‘Umar al Ashraf, his progeny continued only from Abu ‘Abdullah Muhammad. The line of Abu ‘Abdullah Muhammad continued from two people: ‘Umar and ‘Ali.
‘Abbas al Qummi elaborated further:
Take note that ‘Umar al Ashraf married Umm Salamah bint Imam Hassan. It has been reported in the books of genealogy that the line of ‘Umar al Ashraf continued from one person only, i.e. ‘Ali al Asghar al Muhaddith—who reported hadith from al Sadiq. His line continued then from three of his sons: Abu ‘Ali Qasim, ‘Umar al Shajari, and Abu Muhammad Hassan. Take note as well that ‘Umar al Ashraf is the grandfather of ‘Alam al Huda Sayed al Murtada and Sayed al Radi’s mother.
He says in another place:
As for ‘Umar ibn ‘Ali, titled al Ashraf, he was greatly respected and admired, magnanimous… Abu al Jarud ibn al Mundhir reported, “I said to Abu Jafar al Baqir ‘alayh al Salam, ‘Which of your brothers is most beloved to you?’ He replied, ‘As for ‘Abdullah, he is my hands; ‘Umar is my eyes, and Zaid is my tongue with which I speak. As for Hussain, he is patient, tolerant, walking on the earth with no pride.’”
Ibn al Tiqtaqa mentioned about the progeny of ‘Umar ibn ‘Ali ibn Zayn al ‘Abidin:
‘Umar al Ashraf had five children, from who his progeny continued and those whose line ended. They are: Muhammad, Musa, Jafar, ‘Ali, ‘Ali al Asghar al Muhaddith. The line of Muhammad ibn ‘Umar al Ashraf ended with ‘Ali ibn Muhammad ibn ‘Umar ibn Muhammad. The line of ‘Ali al Asghar continued from three of the children of Qasim: Mu’aqqib, ‘Umar al Shajari, and Abu Muhammad Hassan.
Thus we find a third personality from the progeny of the fourth Imam Zayn al ‘Abidin to be granted the name Umar.
Discussion on his lineage has already passed under the progeny of ‘Umar al Ashraf and ‘Umar al Shajari.
Ibn ‘Inabah says:
As for ‘Umar al Shajari ibn ‘Ali ibn ‘Umar al Ashraf, his line continued from one person only: Abu ‘Abdullah Muhammad. The line of Abu ‘Abdullah Muhammad continued from two sons: ‘Umar and ‘Ali.
Muhammad ibn al A’lami al Ha’iri mentioned him in Tarajim A’lam al Nisa’ when discussing the daughter of Hassan ibn ‘Ubaidullah ibn Ismail ibn Jafar al Tayyar.
Ibn ‘Inabah wrote in ‘Umdat al Talib while discussing the progeny of Hussain Dhu al Dam’ah ibn Zaid al Shahid:
As for Yahya Abu Hussain ibn Dhi al Dam’ah, his progeny is vast. It continued from 7 sons; 3 of which left small progenies: Qasim, Hassan al Zahid, and Hamzah; and 4 having large progenies: Muhammad al Asghar al Aqsasi, ‘Isa, Yahya ibn Yahya, and ‘Umar ibn Yahya.
At another juncture he elaborated:
As for ‘Umar ibn Yahya ibn Hussain Dhi Dam’ah, he had the largest progeny than all of his brothers.
Ibn Tiqtaqa said in al Asili:
As for ‘Umar ibn Yahya he is Sayed and a leader. His progeny continued from three.
He from the progeny of ‘Umar ibn Yahya mentioned previously.
Ibn Tiqtaqa said in al Asili:
As for Abu ‘Ali ‘Umar al Ra’is ibn Hussain al Naqib, he is the leader of the Hujjaj. It was he who resolved (matters) and negotiated with the Qaramitah, and returned the Hajar al Aswad. He performed 12 Hajj. He passed away in Baghdad and the market place was closed on the day of his demise; every single person attending his funeral. He left behind 13 sons, every single one of them named Muhammad.
Ibn ‘Inabah too said something quite similar.
Ibn ‘Inabah wrote in ‘Umdat al Talib:
As for ‘Umar ibn Hassan (al Aftas) he participate in (the Battle of) Fakh. His progeny continued from ‘Ali only. ‘Ali ibn ‘Umar’s line continued from 5: Ibrahim, ‘Umar in Azerbaijan… As for ‘Umar ibn ‘Ali ibn Hassan al Aftas, amongst his children is Hamzah ibn Muhammad.
Ibn Tiqtaqa said in al Asili:
The progeny of Hassan al Aftas continued from 5: ‘Ali, ‘Umar, Hassan, ‘Abdullah, and Hassan al Makfuf.
Ibn ‘Inabah said:
As for Hussain ibn al Aftas: his mother was—according to what Abu Hassan al ‘Umari has said—was from the progeny of ‘Umar (ibn al Khattab), i.e. the daughter of Khalid ibn Abi Bakr ibn ‘Abdullah ibn ‘Umar bin al Khattab.
In Nasab Qurash it is recorded:
His mother was Juwairiyah bint Khalid ibn Abi Bakr ibn ‘Ubaidullah ibn ‘Abdullah ibn ‘Umar ibn al Khattab.
He is from the progeny of ‘Umar al Atraf ibn ‘Ali ibn Abi Talib.
Ibn ‘Inabah wrote in ‘Umdat al Talib:
As for ‘Umar al Manjurani ibn Muhammad, attributed to the city of Manjuran in Balkh… He was the first of the Alawis to settle there and had four sons.
Al Irbili has stated in Kashf al Ghummah:
As for his (Musa al Kazim’s) children, it has been said that he had 20 sons and 18 daughters. The names of his sons: ‘Ali al Rida, Zaid, Ibrahim, ‘Aqil, Harun, Hassan, Hussain, ‘Abdullah, Ismail, ‘Ubaidullah, ‘Umar… It has been said that it is Muhammad in place of ‘Umar.
Al Irbili then repeated the same statement on the authority of al Janabidhi, who also mentioned the name ‘Umar but added to them Abu Bakr.
He is the great grandson of ‘Umar ibn ‘Ali, the son of Amir al Mu’minin.
‘Abbas al Qummi mentioned him while discussing the children of Hassan ibn Jafar ibn Hassan al Muthanna:
He is the one who did not participate in the battle of Fakh. He left behind a number of daughters and 5 sons. They were Sulaiman, Ibrahim, Muhammad, ‘Abdullah, and Jafar. Amongst his daughters was Fatimah al Kubra, commonly knwn as Umm Jafar. She was married to ‘Umar ibn ‘Abdullah ibn Muhammad ibn ‘Imran ibn ‘Ali ibn Abi Talib.
‘Imran appears in the original text, which appears to be a mistake as Sayyidina ‘Ali radiya Llahu ‘anhu is not known to have any son by the name of ‘Imran. The correct name should be ‘Umar and not ‘Imran.
The great grandson of Amir al Mu’minin, was also named ‘Umar.
Ibn ‘Inabah mentions under the progeny of ‘Umar al Atraf:
‘Umar passed away in Yanbu’ when he was 77 years old. His progeny continued from one of his children only: his son Muhammad. The line of Muhammad continued from four of his sons: ‘Abdullah, ‘Ubaidullah and ‘Umar—whose mother was Khadijah bint Zayn al ‘Abidin ‘Ali ibn Hussain; and from Jafar—whose mother was an Umm Walad.
One cannot help but stop and marvel at the love the Ahlul Bayt had for the Noble Companions of the Prophet salla Llahu ‘alayhi wa sallam, especially for Sayyidina ‘Umar radiya Llahu ‘anhu. There is scarcely a generation except that it contains a personality from the Ahlul Bayt named ‘Umar. Together we have analysed what each of the genealogists, Ibn ‘Inabah and Ibn Tiqtaqa in particular, have had to say; can there be any doubt thereafter that the Ahlul Bayt had a deep love for Sayyidina ‘Umar ibn al Khattab radiya Llahu ‘anhu, such that they didn’t abandon his name in any generation. Sayyidina ‘Ali radiya Llahu ‘anhu remarried after the demise of Sayyidah Fatimah radiya Llahu ‘anha and shortly thereafter he was blessed with a son who he name Muhammad (ibn al Hanafiyyah). When he was blessed with another son thereafter, he was asked what he would name him and he replied, “After Muhammad, he can only be named Abu Bakr.” Later when a third son was born he named him ‘Umar, and when the next son was born he named him ‘Uthman. He was questioned about this action of his, “How could you name your children after others first and your uncle (‘Abbas) last?” He answered, “Just as Allah and His Rasul placed him last.” He named his son born thereafter from Umm al Banin al Kilabiyyah after his uncle ‘Abbas radiya Llahu ‘anhu.
If one reads through the table of contents of Al Asili fi Ansab al Talibiyin by Mahdi al Raja’i he will find the name ‘Umar repeatedly, sixteen times to be precise, all from the progeny of ‘Ali ibn Abi Talib. We reproduce it here in the same order he cited them in:

 Ibn ‘Inabah: His name is al Sharif Ahmed ibn Ali ibn Hussain ibn Ali ibn Mahna ibn ‘Inabah al Asghar. His lineage links up with Musa (al Jawn) ibn ‘Abdullah (al Mahd). He was born in 748 A.H and died in 828 A.H in Kirman (Iran). Amongst his renowned works are: ‘Umdat al Talib fi Ansab Abi Talib. He has other works in genealogy as well such as: ‘Umdat al Talib al Sughra called Musha’sha’iyyah; al Fusul al Fakhriyyah fi al Usul al Bariyyah; Bahr al Ansab fi Nasab Bani Hashim; Tuhfat al Talib fi al Nasab. The author of Bihar al Anwar said about him, “He is amongst the pioneers of the Imami scholars.” ‘Abbas al Qummi al Najafi wrote under his biography in al Kuna wa al Alqab, “Sayyid, an eminent ‘Allamah, genealogist, student of al Sayed Taj al Din ibn Mu’ayyah—the genealogist—and teacher of al Shahid al Awwal and his student. He was from the scholars of the Imamiyyah, in fact amongst the most eminent of them. He studied Fiqh, Hadith, Genealogy, language, and many other subjects under al Sayed Ibn Mu’ayyah for twelve years.”

 Ibn ‘Asakir has reported a narration from Muhammad ibn Salam: I asked ‘Isa ibn ‘Abdullah ibn Muhammad ibn ‘Umar ibn ‘Ali ibn Abi Talib, “How did your grandfather ‘Ali name (his son after) ‘Umar?” He replied, “My father informed me from his father from ‘Umar ibn ‘Ali ibn Abi Talib who said, ‘I was born after ‘Umar ibn al Khattab was appointed Khalifah and ‘Ali told him that a son had been born to him the previous night. ‘Umar asked, ‘Gift him to me.’ ‘Ali replied, ‘He is yours.’ ‘Umar said, ‘I name him ‘Umar and I gift to him my slave Muriq.’” [Tarikh Dimashq 48/203]
 Ibn al Tiqtaqa mentioned it as Dhu al ‘Ibrah while other sources mention it as Dhu al Dam’ah.
