Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the Prophet (peace and blessings be upon him) married Ali (may Allah be pleased with him) to Fatimah (may Allah be pleased with her), she said: You have married me to a needy man who has no wealth. He (peace and blessings be upon him) said to her: "Are you not pleased that Allah looked upon the earth and chose two men from it, making one of them your father and the other your husband?"
