Narrated to us Abu Bakr ibn Abi Shaybah, narrated to us 'Abd al-A'la, from Ma'mar, from al-Zuhri, from Salim, from Ibn 'Umar, that they used to be beaten during the time of the Messenger of Allah (peace be upon him) when they bought food in bulk (jizafan) if they sold it in its place until they had moved it.
