Qays (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) said to Sayyidah Asma' (may Allah be pleased with her): "We preceded you in the emigration (Hijrah)." She replied: "By Allah! You certainly preceded us in the emigration, (while) we were staying (in Abyssinia) among people who were naked and barefoot, and you were with the Messenger of Allah (peace and blessings be upon him); he would teach those of you who did not know, benefit those of you who knew, and urge you to the loftiest morals." And she said: "I will surely go to the Messenger of Allah (peace and blessings be upon him) and inform him of this." (When she mentioned it,) he (peace and blessings be upon him) said: "For the people there is one emigration, while for you (the people of the ship) there are two emigrations."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Sufyan except Muhammad bin Abi Umar."
