Sayyidah Salma (may Allah be pleased with her) reported that the Messenger of Allah (peace and blessings be upon him) sent a goat to Abu Rafi' (may Allah be pleased with him), and that was on the day of the Trench, as far as I know. Abu Rafi' (may Allah be pleased with him) roasted it, put it in a basket and set off with it, and the Prophet (peace and blessings be upon him) met him while returning from the Trench. He ((peace and blessings be upon him)) said to him: "O Abu Rafi', give me the foreleg." So I gave it to him ((peace and blessings be upon him)). Then he ((peace and blessings be upon him)) said: "O Abu Rafi', give me the foreleg." So I gave it to him ((peace and blessings be upon him)). Then he ((peace and blessings be upon him)) said: "O Abu Rafi', give me the foreleg." So he said: O Messenger of Allah, does a goat have more than two forelegs? He ((peace and blessings be upon him)) said: "Had you kept quiet, you would have kept giving me whatever I asked for."
