Abd al-Rahman bin Abi al-Zinad (may Allah have mercy on him) narrates from his father (may Allah have mercy on him) that the Quraysh in the Jahiliyyah used to hold themselves above the earnings of the cupper out of nobility; yet had it been unlawful, the Prophet (peace and blessings be upon him) would not have said: "Use it in the fodder of the orphan's camel."
