It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade meeting trading caravans on the way before they reach the market, bidding merely to raise the price, and withholding the milk of milking animals. He also forbade that a woman demand the divorce of her (Muslim) sister, and that a man bid over the price set by his (Muslim) brother.
