It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "The Messenger of Allah (peace and blessings be upon him) left behind neither gold nor silver, nor any goat or camel; he (peace and blessings be upon him) left nothing (behind him) except some barley. We kept eating from it for a long time, then I measured it, and I wished that I had not measured it."
No one narrated it from Hisham bin Urwah (may Allah have mercy on him) except Ma'mar (may Allah have mercy on him), no one from Ma'mar (may Allah have mercy on him) except Hisham bin Yusuf (may Allah have mercy on him), and no one from Hisham (may Allah have mercy on him) except Ali bin Bahr (may Allah have mercy on him).
