Ibn Abi Mulaykah narrates: When Makkah was conquered, Ikrimah bin Abi Jahl fled and set out on a sea voyage. The sea became stormy, and the sailors and the people at sea began calling upon Allah Almighty and seeking His help. Ikrimah bin Abi Jahl said, "What is this?" They said, "This is a place where none but Allah Almighty can be of benefit." Ikrimah said, "Then that is the God of Muhammad (peace and blessings be upon him), to whom he calls us. Take us back!" So they returned, and he came back and accepted Islam. His wife had already accepted Islam before him, so the two of them remained upon their marriage.
Tabarani recorded it.
