قام رسول الله صلى الله عليه وسلم يوما فينا خطيبا بماء يدعى خما، بين مكة والمدينة، فحمد الله وأثنى عليه، ووعظ وذكر. ثم قال: أما بعد، ألا أيها الناس فإنما أنا بشر يوشك أن يأتي رسول ربي فأجيب، وأنا تارك فيكم ثقلين: أولهما كتاب الله، فيه الهدى والنور، فخذوا بكتاب الله، واستمسكوا به. فحث على كتاب الله ورغب فيه. ثم قال: وأهل بيتي، أذكركم الله في أهل بيتي، أذكركم الله في أهل بيتي، أذكركم الله في أهل بيتي. فقال له حصين: ومن أهل بيته يا زيد؟ أليس نساؤه من أهل بيته؟ قال: نساؤه من أهل بيته، ولكن أهل بيته من حرم الصدقة بعده. قال: ومن وهم؟ قال: هم آل علي وآل عقيل وآل جعفر وآل عباس. قال: كل هؤلاء حرم الصدقة؟ قال: نعم.
One day Allah’s Messenger salla Llahu ‘alayhi wa sallam stood up to deliver a sermon near a watering place known as Khumm, situated between Makkah and Madinah. He praised and extolled Allah, and counselled and exhorted us. Then he said, “O people! I am but a human being. The messenger of my Lord (i.e. the angel of death) is on the verge of coming, and I will soon respond to his call. I am leaving with you two weighty things: The first being the Book of Allah. In it contains guidance and nur (light); so take the Book of Allah and adhere to it.” He exhorted (us) (to hold fast) to the Book of Allah and encouraged us (to adhere to it). Then he said, “(The second thing is) the members of my household; I remind you, by Allah, of (your duties towards) the members of my family. I remind you, by Allah, of (your duties towards) the members of my family. I remind you, by Allah, of (your duties towards) the members of my family.”
He (Hussain) said to Zaid, “Who are the members of his household? Are his wives not members of his family?”
Thereupon Zaid said, “His wives are members of his household, but the members of his family are (also) those upon whom accepting Zakat is haram.”
He asked, “Who are they?”
Zaid replied, “They are (from) the offspring of ‘Ali, ‘Aqil, Jafar, and ‘Abbas.” Hussain said, “Is (accepting) Zakat haram upon these (people)?”
Zaid said, “Yes.”
This hadith has been transmitted by Zaid ibn Arqam, Abu Sa’id, Zaid ibn Thabit, Jabir, Hudhayfah ibn Asid, and ‘Ali radiya Llahu ‘anhum.
The Hadith of Zaid ibn Arqam
Imam Muslim, Ahmed, Ibn Khuzaimah, and others narrate this hadith from Yazid ibn Hayyan — from Zaid ibn Arqam. The hadith appears in an abridged form in some of these versions.
Imam al Tabarani narrates:
حدثنا علي بن عبد العزيز، ثنا عمرو بن عون الواسطي، ثنا خالد بن عبد الله، عن الحسن بن عبيد الله، عن أبي الضحى، عن زيد بن أرقم قال: قال رسول الله صلى الله عليه وسلم: إني تارك فيكم الثقلين: كتاب الله وعترتي أهل بيتي، وإنهما لن يتفرقا حتى يردا علي الحوض وهذا سند صحيح. والحسن بن عبيد الله هو ابن عروة. وخالد بن عبد الله هو الواسطي.
‘Ali ibn ‘Abdul ‘Aziz informed us — ‘Amr ibn ‘Awn al Wasiti informed us — Khalid ibn ‘Abdullah informed us — from al Hassan ibn ‘Ubaidullah — from Abi al Duha — from Zaid ibn Arqam radiya Llahu ‘anhu who said that the Prophet salla Llahu ‘alayhi wa sallam said, “I am leaving with you two weighty things: 1) the Book of Allah, and 2) my progeny and the members of my household. These two will never separate from each other until they meet me at the hawd (pond). This (hadith) has an authentic chain. Al Hassan ibn ‘Ubaidullah is ibn ‘Urwah. And Khalid ibn ‘Abdullah is (Khalid ibn ‘Abdullah) al Wasiti.’
Al Hakim al Naisaburi and al Tabarani narrate this hadith with a different chain of transmission from Hassan. Al Hakim (also) authenticated the hadith and al Dhahabi concurred.
Imam Ahmed (and others) narrates from Israʾil — from ‘Uthman ibn al Mughirah — from ‘Ali ibn Rabi’ah who said, “I met Zaid ibn Arqam whilst he was entering the residence of al Mukhtar or leaving. I said to him, “Did you hear the Prophet salla Llahu ‘alayhi wa sallam saying: ‘I am leaving with you two weighty things.’ I said, ‘Yes.’” According to others (besides Imam Ahmed) the wording (of the hadith) is, “I am leaving with you two weighty things: the Book of Allah and my progeny.” He said, ‘Yes.’
The chain of transmission (of this hadith) is authentic.
Al Albani authenticated this hadith.
The remaining chains of transmission are not authentic. Except for one of ‘Ali’s radiya Llahu ‘anhu versions, it can potentially be graded as Hassan (fair). They have all been mentioned in the original work.
