Abu Bakr b. Aba Maryam said that Miqdam b. Ma'dikarib had a slave girl who sold milk the price of which was taken by Miqdam. Some people said, “Glory be to God! Do you sell milk and accept what is paid for it?” He replied that he did, and asked what harm there was in that, for he had heard God’s Messenger say, “A time is certainly coming to mankind when only the dinar and the dirham will be of use.” Ahmad transmitted it.
