Abu Malik al-Ashja'i said: I was sitting with Muhammad bin Hatib (may Allah be pleased with him) when he said: The Messenger of Allah (peace and blessings be upon him) said: "I have seen a land of date palms, so go out." So Hatib and Ja'far (bin Abi Talib) set out by sea towards the Negus, and I was born on the ship itself.
