Yazid bin Hayyan said, "I set out with Husayn bin Sabra and Umar bin Muslim to visit Zayd bin Arqam. When we sat down with him, Husayn said to him, 'Zayd, you have been granted much good. You saw the Messenger of Allah ﷺ, heard his speech, fought alongside him, and prayed behind him. You have been granted much good indeed, Zayd. Tell us what you heard from the Messenger of Allah ﷺ.'"Zayd replied, "Nephew, by Allah, I have grown old and my time is long past. I have forgotten some of what I used to retain from the Messenger of Allah ﷺ. So whatever I tell you, accept it, and what I do not, do not press me for it."Then he said, "One day the Messenger of Allah ﷺ stood up among us to deliver a sermon at a watering place called Khumm, between Makkah and Madinah. He praised Allah and extolled Him, then admonished and reminded us. Then he said:'To proceed. People, I am only a human being, and the messenger of my Lord ﷺ is about to come to me and I will answer. I am leaving among you two weighty things. The first is the Book of Allah, in which is guidance and light, so take hold of the Book of Allah and cling to it.' He urged us to follow the Book of Allah and encouraged us 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 asked him, "Who are the people of his household, Zayd? Are his wives not among the people of his household?"Zayd answered, "His wives are among the people of his household, but the people of his household are those for whom receiving charity is forbidden after him."Husayn asked, "And who are they?"Zayd replied, "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."
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 خلفه، لقد لقيت يا زيد خيرا كثيرا، حدثنا يا زيد ماسمعت من رسول الله ﷺ قال: يا ابن أخي والله لقد كبرت سني، وقدم عهدي، ونسيت بعض الذي كنت أعي من رسول الله ﷺ، فما حدثتكم فاقبلوا، وما لا فلا تكلفونيه ثم قال: قام رسول الله ﷺ 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 ﷺ 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 هم؟ قال: هم آل علي وآل عقيل، وآل جعفر، وآل عباس قال: كل هؤلاء حرم الصدقة؟ قال: نعم.
