Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Rafi’ (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him) sent a man from Banu Makhzum to collect charity. He said to Abu Rafi’ (may Allah be pleased with him): “Come along with me so that you may also get something (of wealth, etc.).” He replied: “I cannot make any (decision) without first asking the Messenger of Allah (peace and blessings be upon him).” He went to the Noble Prophet (peace and blessings be upon him) and asked him. The Prophet (peace and blessings be upon him) said: “Indeed, charity is not lawful for us, and the freed slaves of a people are considered among them (so the same ruling applies to them).”
