Malik related to me from Umar ibn Abd ar-Rahman ibn Dalaf al-Muzani from his father that a man from the Juhayna tribe used to buy camels before people set out for hajj and sell them at a higher price. Then he travelled quickly and used to arrive in Makka before the others who set out for hajj. He went bankrupt and his situation was put before Umar ibn al-Khattab, who said, "O People! al-Usayfi, al-Usayfi of the Juhayna, was satisfied with his deen and his trust because it was said of him that he arrived before the others on hajj. He used to incur debts which he was not careful to repay, so all of his property has been eaten up by it. Whoever has a debt against him, let him come to us tomorrow and we will divide his property between his creditors. Beware of debts! Their beginning is a worry and their end is destitution. "
