Al-Zuhri said: Abd al-Rahman bin Awf (may Allah be pleased with him) gave half of his wealth in charity in the time of the Messenger of Allah (peace and blessings be upon him), namely four thousand; then he gave forty thousand in charity; then he gave forty thousand dinars in charity; then he provided five hundred horses in the path of Allah; then he provided one thousand five hundred camels in the path of Allah. Most of his wealth came from trade.
