It was narrated from Ibn Abi Rafi’, from his father, that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم appointed a man from Banu Makhzum to collect Sadaqah. Abu Rafi’ wanted to go with him, but the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “The Sadaqah is not permissible for us, and the freed slave of a people is one of them.” (Sahih)
