Abdul-Muttalib bin Rabia reported,
Rabia bin Harith and Abbas bin Abdul-Muttalib met and said, "By Allah, if we sent these two young men," meaning me and Fadl bin Abbas, "to the Messenger of Allah ﷺ to speak with him so that he might appoint them over these charity collections, they could deliver what others deliver and earn what others earn."While they were discussing this, Ali bin Abu Talib came up and stood beside them. They mentioned the matter to him.Ali bin Abu Talib said, "Do not do it. By Allah, he will not do it."Rabia bin Harith turned on him and said, "By Allah, you are only doing this out of envy toward us. By Allah, you obtained the honor of marrying into the Messenger of Allah's family ﷺ and we did not envy you for it."Ali said, "Send them, then."So we set off, and Ali lay down. When the Messenger of Allah ﷺ had prayed the noon prayer, we went ahead of him to his chamber and stood there until he arrived. He took us by the ears and said, "Out with whatever you are concealing."Then he entered, and we entered with him. He was at that time with Zaynab bint Jahsh.We each tried to leave the talking to the other, then one of us spoke up and said, "Messenger of Allah, you are the most dutiful and most kind of people, and we have reached the age of marriage. We have come so that you may appoint us over some of these charity collections. We will deliver to you as others deliver and earn as others earn."He remained silent for a long time, until we wanted to speak to him again. Zaynab began signaling to us from behind the curtain not to speak to him.Then he said, "Charity is not permissible for the family of Muhammad. It is merely the impurities of the people. Call for me Mahmiyah," who was in charge of the fifth, "and Nawfal bin Harith bin Abdul-Muttalib."They came to him. He said to Mahmiyah, "Marry your daughter to this young man," meaning Fadl bin Abbas, and he married her to him.He said to Nawfal bin Harith, "Marry your daughter to this young man," meaning me, and he married her to me.Then he said to Mahmiyah, "Pay such-and-such as their dowry from the fifth."Zuhri said, "He did not name the amount to me."

Sahihعن عبد المطلب بن ربيعة بن الحارث حدثه، قال
اجتمع ربيعة بن الحارث والعباس بن عبد المطلب فقالا: والله لو بعثحدثنا هذين الغلامين قالا لي وللفضل بن عباس إلى رسول الله ﷺ فكلماه فأمرهما على هذه الصدقات فأديا ما يؤدي الناس وأصابا مما يصيب الناس، قال: فبينما هما في ذلك جاء علي بن أبي طالب فوقف عليهما فذكرا له ذلك، فقال علي بن أبي طالب: لا تفعلا فوالله ما هو بفاعل، فانتحاه ربيعة بن الحارث، فقال: والله ما تصنع هذا إلا نفاسة منك علينا! فوالله لقد نلت صهر رسول الله ﷺ فما نفسناه عليك! قال علي: أرسلوهما فانطلقا، واضطجع علي قال: فلما صلى رسول الله ﷺ الظهر سبقناه إلى الحجرة فقمنا عندها حتى جاء فأخذ بآذاننا، ثم قال: أخرجا ما تصرران. ثم دخل ودخلنا عليه، وهو يومئذ عند زينب بنت جحش قال: فتواكلنا الكلام ثم تكلم أحدنا، فقال: يا رسول الله أنت أبر الناس وأوصل الناس، وقد بلغنا النكاح فجئنا لتؤمرنا على بعض هذه الصدقات فنؤدي إليك كما يؤدي الناس ونصيب كما يصيبون قال: فسكت طويلا حتى أردنا أن نكلمه. قال: وجعلت زينب تلمع علينا من وراء الحجاب أن لا تكلماه. قال: ثم قال: إن الصدقة لا تنبغي لآل محمد؛ إنما هي أوساخ الناس ادعوا لي محمية- وكان على الخمس- ونوقل بن الحارث بن عبد المطلب. قال: فجاءه، فقال لمحمية: أنكح هذا الغلام ابنتك. للفضل بن عباس فأنكحه، وقال لنوفل بن الحارث: أنكح هذا الغلام ابنتك. لي فأنكحني، وقال لمحمية: أصدق عنهما من الخمس كذا وكذا. قال الزهري: ولم يسمه لي.
Muslim narrated it in the Book of Zakat (1072) from Abdullah bin Muhammad bin Asma Dubai, who said, Juwayria narrated to us, from Malik, from Zuhri, that Abdullah bin Abdullah bin Nawfal bin Harith bin Abdul-Muttalib told him, that Abdul-Muttalib bin Rabia bin Harith told him, and he mentioned it.Malik mentioned this hadith in the Book of Sadaqah (13) as a balagh, and Muslim mentioned it through the narration of Juwayria, who is the son of Asma Dubai Basri, one of the narrators of the Muwatta. However, I did not find this hadith with this level of detail from Malik in the existing copies of the Muwatta except through the narration of Juwayria. Abu Dawud (2985), Nasai (2609), Ibn Khuzayma (2344), and Imam Ahmad (17518) all narrated it through various routes from Yunus, from Zuhri with his chain of transmission, in similar wording, both at length and in brief. Perhaps Malik abridged this hadith and omitted the detail from it, and Juwayria bin Asma was unaware of that, because he returned to Basra and died six years before Malik. And Allah knows best.His saying, "So Rabia approached him," means he made his way toward him. His saying, "Bring out what you have been withholding," means what you two have been holding back in your hearts of speech. His saying, "She was gesturing," means she was signaling with her garment or with her hand. And Zuhri's statement, "He did not name it for me," means that his teacher did not specify to him the amount of the dowry that the Messenger of Allah had named for the two of them.This hadith contains evidence that sadaqah is forbidden to the members of the Household, whether the reason be employment, poverty, destitution, or any of the other eight categories. This is the view held by the majority of scholars, including Malik, Shafii, and Ahmad. Abu Hanifa permitted it, on the grounds that the wage corresponds to the work performed.Some scholars understood the hadith to prohibit appointing a member of the Household as a zakat collector, but the correct view is that the hadith does not prohibit this. Rather, it only prohibits taking wages from zakat funds, but if they were given from another source, that would be permissible. Indeed, Ali bin Abu Talib employed some of the Banu Abbas for that purpose.As for what has been narrated from Ibn Abbas, who said, Nawfal bin Harith sent his two sons to the Messenger of Allah 
, and he said to them, "Go to your uncle, perhaps he will make use of you in collecting the sadaqahs, so that you might obtain something and be able to marry." They then met Ali, who said, "Where are you two headed?" So they told him of their need, and he said to them, "Go back." So they went back. When evening came, he instructed them to go to the Prophet of Allah . When they reached the door, they sought permission to enter, and the Messenger of Allah said to Ayesha, "Let down your curtain, so that my two cousins may come in to see me." They then told the Prophet of Allah of their need, and the Prophet of Allah said to them, "Nothing from the sadaqahs is permissible for you, O members of the Household, nor even the water used to wash hands after eating. You have, in the fifth of the fifth, enough to enrich you or suffice you."This narration is daif jiddan. Tabarani narrated it in Al-Kabir (11/217) from Muaz bin Muthanna, who said, Musaddad narrated to us, who said, Mutamir narrated to us, saying, I heard my father narrating from Hanash, from Ikrima, from Ibn Abbas, and he mentioned it. Hanash, with a fatha on the ha and the nun, is Husayn bin Qays Rahbi, who is daif jiddan, and the majority of scholars have declared him daif. Haythami mentioned this in Al-Majma (3/91) and noted this defect in it.
