Abu Sa'id al-Khudri reported God’s Messenger as saying, “If anyone pays in advance for an article he may not transfer, it to someone else before he receives it.”
Ibn ‘Abbas reported God’s Messenger as saying to those who measured commodities by capacity and those who measured by weight, “You have been put in charge of two matters because of which peoples of the past before your time perished.”
Ibn ‘Umar reported the Prophet as saying, “The measure of capacity is that used by the people of Medina and the measure of weight is that used by the people of Mecca.” Abu Dawud and Nasa’i transmitted it.
