Sayyiduna Muhammad bin Hatib (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "I have seen (in a dream, as the place of migration) a land with date palms, so go out." The narrator says: Sayyiduna Hatib (may Allah be pleased with him) and Sayyiduna Ja'far (may Allah be pleased with him) set out by the sea route towards the Negus. The narrator says: I was born on that ship.
Ahmad and al-Tabarani recorded it, and its narrators are the narrators of the Sahih.
