Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: A man, or a young man, came to the Prophet (peace and blessings be upon him) and said that he had married a woman. He (peace and blessings be upon him) said: "Did you look at her? For there is something in the eyes of the Ansar." He said: I have looked at her. He said: "How much dower did you give?" He mentioned something. He (peace and blessings be upon him) said: "It is as if you carve gold and silver out of the side of these mountains! We have nothing today to give you, but I will send you in a direction where you will obtain something." And he (peace and blessings be upon him) sent him with an expedition towards Banu Abs. Then he came to the Messenger of Allah (peace and blessings be upon him) and said: My she-camel has become too exhausted to get up. So the Messenger of Allah (peace and blessings be upon him) took support from his hand and stood up, and struck it with his foot. Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: By the One in whose hand my soul is, it went ahead of the other mounts.
