Musnad Ahmad 27:1919

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from Salim, from Ibn 'Umar, who said: "I saw the people during the time of the Messenger of Allah, may Allah bless him and grant him peace, being struck if a man bought food in bulk, for selling it before he moved it to his own place."
