It is reported about Sayyidah Asma bint Abi Bakr (may Allah be pleased with her) that in the blessed time of the Prophet (peace and blessings be upon him), she used to pay, on behalf of the members of her household, both the free and the slaves among them, two mudds of wheat or one sa' of dates; this was by the "mudd" with which the people conducted their dealings.
