man outbid the bid of his brother." This situation is not without four categories: One of them is that there is explicit satisfaction with the sale from the seller. In this case, bidding by anyone other than that buyer is forbidden, and this is what the prohibition addresses. The second is that something is shown by him that indicates a lack of satisfaction; thus, bidding is not forbidden, because the Prophet (peace and blessings of Allah be upon him) sold to the highest bidder. Anas narrated that a man from the Ansar complained to the Prophet (peace and blessings of Allah be upon him) of hardship and poverty. He said to him, "Is there anything left for you?" He replied, "Yes, a bowl and a saddle blanket (5)." He said, "Bring them to me." He brought them to him, and he said, "Who will buy these?" A man said, "I will take them for one dirham." The Prophet (peace and blessings of Allah be upon him) said, "Who will offer more than a dirham? Who will offer more than a dirham?" A man gave him two dirhams, and he sold them to him. It was recorded by al-Tirmidhi (6), who said it is a hassan (sound) hadith. This is also the consensus of the Muslims; they sell in their markets by auction. The third is that nothing is found from him that indicates satisfaction [nor] (7) a lack thereof, so bidding (8) is not forbidden, nor is increasing the bid, by inferring from the hadith of Fatimah bint Qays when she mentioned to the Prophet (peace and blessings of Allah be upon him) that Mu'awiyah and Abu Jahm had proposed to her, and he advised her to marry Usamah (9). He had forbidden proposing over the proposal of one's brother, just as he forbade bidding over the bid of one's brother, so what is permitted in one of them is permitted in the other.
