Hadith 2353

Imam Abu Bakr, may Allah have mercy on him, says that in the narration of Hazrat Urwah from Sayyidah Aisha, may Allah be pleased with her, the Prophet Muhammad, peace and blessings be upon him, said: "Our inheritance will not be distributed; whatever wealth we leave behind will be charity. Indeed, the family of Muhammad will eat from this wealth." In this way, the Prophet Muhammad, peace and blessings be upon him, informed that his family will eat from his charity because his charity is not obligatory charity (zakat).
