Musnad Ahmad 27:2012

He said: I read to my father: Hammad ibn Khalid al-Khayyat narrated to us, Ibn Abi Dhi’b narrated to us, from al-Zuhri, from Salim, from his father, who said: "When we used to buy food in bulk during the time of the Messenger of Allah, may Allah bless him and grant him peace, we were forbidden from selling it until we had moved it to our own dwellings."
