Ibn Abi Mulaykah said: On the day of the Conquest of Makkah, Sayyiduna Ikrimah bin Abi Jahl (may Allah be pleased with him) fled and boarded a ship at sea. A storm arose at sea, and the sailors and those at sea began calling upon Allah, the Mighty and Majestic, and seeking His help. He asked: What is this? He was told: This is a place where nothing avails except Allah. Ikrimah said: This, then, is the God of Muhammad to whom he calls us; take us back to him. So he returned and accepted Islam. His wife had already accepted Islam before him, so the two of them remained upon their marriage.
