It is narrated on the authority of 'Abdullah ibn' Umar (may Allah be pleased with him) that the Messenger of Allah (may peace be upon him) passed by a heap of grain. When Mubarak entered it, he saw that it was a waste of grain. He (peace and blessings of Allaah be upon him) said to him: Sell it separately and separately. He who betrayed us is not one of us.
