It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) that Sayyiduna Ali (may Allah be pleased with him) mentioned the daughter of Abu Jahl (in connection with marriage). This reached the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Fatimah is but a part of me; whatever hurts her hurts me, and whatever distresses her distresses me."
