Yazid bin Hayan reported,

Husayn bin Sabra, Umar bin Muslim, and I went to Zayd bin Arqam. When we sat down with him, Husayn said to him, "Zayd, you have encountered much good. You saw the Messenger of Allah ﷺ, heard his speech, fought alongside him, and prayed with him. You have indeed seen much good, Zayd. Tell us, Zayd, what you heard from the Messenger of Allah ﷺ."Zayd replied, "Nephew, by Allah, I have grown old, my time is long past, and I have forgotten some of what I used to retain from the Messenger of Allah ﷺ. So whatever I tell you, accept it, and whatever I do not, do not press me for it."Then he said, "One day the Messenger of Allah ﷺ stood up to deliver a sermon to us at a watering place called Khumm, between Mecca and Medina. He praised Allah Almighty and glorified Him, then admonished and reminded us. Then he said, 'Now then, people, I am only a human being, and the messenger of my Lord is about to come to me and I will respond. I am leaving among you two weighty things. The first is the Book of Allah , in which there is guidance and light, so take hold of the Book of Allah Almighty and cling to it.' He urged people to follow the Book of Allah and encouraged them in it. Then he said, 'And the people of my household. I remind you of Allah regarding the people of my household. I remind you of Allah regarding the people of my household. I remind you of Allah regarding the people of my household.'"Husayn said to him, "Who are the people of his household, Zayd? Are his wives not among the people of his household?"Zayd replied, "His wives are part of his household, but the people of his household are those for whom charity is forbidden after him."Husayn asked, "And who are they?"Zayd said, "They are the family of Ali, the family of Aqeel, the family of Jafar, and the family of Abbas."Husayn asked, "Is charity forbidden to all of these?"Zayd answered, "Yes."

حدثنا إسماعيل بن إبراهيم عن أبي حيان التيمي حدثني

يزيد بن حيان التيمي قال

انطلقت أنا وحصين بن سبرة وعمر بن مسلم إلى زيد بن أرقم فلما جلسنا إليه قال له حصين لقد لقيت يا زيد خيرا كثيرا رأيت رسول الله ﷺ وسمعت حديثه وغزوت معه وصليت معه لقد رأيت يا زيد خيرا كثيرا حدثنا يا زيد ما سمعت من رسول الله ﷺ فقال يا ابن أخي والله لقد كبرت سني وقدم عهدي ونسيت بعض الذي كنت أعي من رسول الله ﷺ فما حدثتكم فاقبلوه وما لا فلا تكلفونيه ثم قال قام رسول الله ﷺ يوما خطيبا فينا بماء يدعى خما بين مكة والمدينة فحمد الله تعالى وأثنى عليه ووعظ وذكر ثم قال أما بعد ألا يا أيها الناس إنما أنا بشر يوشك أن يأتيني رسول ربي عز وجل فأجيب وإني تارك فيكم ثقلين أولهما كتاب الله عز وجل فيه الهدى والنور فخذوا بكتاب الله تعالى واستمسكوا به فحث على كتاب الله ورغب فيه 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 إن نساءه من أهل بيته ولكن أهل بيته من حرم الصدقة بعده قال ومن هم قال هم آل علي وآل عقيل وآل جعفر وآل عباس قال أكل هؤلاء حرم الصدقة قال نعم
