Anas (may Allah be pleased with him) says that whenever the Prophet (peace and blessings be upon him) was asked for anything, he would certainly give it. A man came and asked him, so he (peace and blessings be upon him) ordered that he be given the goats that were between two mountains. When he went back to his people, he said: "O my people! Become Muslims, for Muhammad (peace and blessings be upon him) gives so much that he does not even fear poverty."
