It is narrated from Hazrat Buraidah (may Allah be pleased with him) that when Hazrat Ali (may Allah be pleased with him) sent a proposal of marriage to Hazrat Fatimah (may Allah be pleased with her), the Holy Prophet (peace and blessings be upon him) said that it is necessary to have a wedding feast (walimah). Hazrat Sa'd (may Allah be pleased with him) said, "I am responsible for one ram," and another said, "I am responsible for as much as I have."
