Hussain ibn ‘Ali, the grandson of Rasulullah salla Llahu ‘alayhi wa sallam
He is the Imam, leader, and martyr Sayyidina Hussain ibn ‘Ali ibn Abi Talib al Hashimi, Abu ‘Abdullah radiya Llahu ‘anhu. The grandson of Rasulullah salla Llahu ‘alayhi wa sallam and his rayhanah (sweet smelling flower). He and his brother are the leaders of the youth of Jannat. Some of his virtues have passed while mentioning the virtues of his brother Sayyidina Hassan ibn ‘Ali radiya Llahu ‘anhum.
Jafar ibn Muhammad says:
لم يكن بين الحمل بالحسين و ولادة الحسن إلا طهر واحد
Between Hussain’s conception and Hassan’s birth was only one clean period.
Al Tirmidhi reports from Ya’la ibn Murrah a narration he declares hassan that Rasulullah salla Llahu ‘alayhi wa sallam said:
حسين مني و أنا من حسين أحب الله من أحب حسينا حسين سبط من الأسباط
Zubair ibn Bakkar says―Mus’ab narrated to me saying:
حج الحسين خمسا و عشرين حجة ماشيا
Hussain performed walking Hajj 25 times.
قالوا و كان الحسين فاضلا كثيرا الصلاة و الصوم و الحج و الصدقة و أفعال الخير جميعها
They said, “Hussain was outstanding and performed abundant salah, Hajj, fasting, charity, and all good deeds.”
He was martyred on the Day of Jumu’ah―or Saturday―the day of ‘Ashura’ at Karbala’ in the land of Iraq. People were extremely sorrowful upon his demise and recited plenty eulogies for him.
Sayyidina Hussain radiya Llahu ‘anhu had the following children amongst others: ‘Ali al Akbar, ‘Ali al Asghar, Fatimah, and Sukaynah.
Hafiz says, “A group of early scholars have written many books about Hussain’s martyrdom which contain all types of narrations, authentic and inauthentic. He was martyred on the day of ‘Ashura’ the year 61 A.H. at the age of 65.”
The guarantee of his and his brother’s entry into Jannat has reached the level of tawatur as was noted in his brother’s biography.

 The meaning of his statement, “… are from the asbat,” is [they are] one of the nations in goodness. Asbat in the progeny of Ishaq ibn Ibrahim al Khalil ‘alayh al Salam is like tribes in the progeny of Ismail. The singular is sibt. It is used to refer to an ummah and vice versa.
