It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) that Sayyiduna Ali (may Allah be pleased with him) proposed marriage to the daughter of Abu Jahl. News of this reached the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Fatimah is a part of me; whatever hurts her hurts me, and whatever angers her angers me."
