Abdullah ibn Maslamah ibn Qa'nab narrated to us, Sulayman—meaning ibn Bilal—narrated to us, from Abd al-Majid ibn Suhayl ibn Abd al-Rahman, that he heard Sa'id ibn al-Musayyab narrating that Abu Hurayrah and Abu Sa'id both narrated to him that the Messenger of Allah, peace and blessings be upon him, sent the brother of Banu Adi al-Ansari and appointed him over Khaybar. He returned with fine-quality dates. The Messenger of Allah, peace and blessings be upon him, said to him: "Are all the dates of Khaybar like this?" He said: "No, by Allah, O Messenger of Allah. We buy a sa' for two sa's of mixed dates." The Messenger of Allah, peace and blessings be upon him, said: "Do not do that. Rather, sell them like for like, or sell these and buy with their price from these. And likewise is the case with the scale."
