We received the news of the departure of the Prophet (to Medina) while we were in Yemen. So we went on board a ship but our ship took us away to An-Najashi (the Negus) in Ethiopia. There we met Jaʿfar bin Abi Talib and stayed with him till we came (to Medina) by the time when the Prophet ﷺ had conquered Khaibar. The Prophet ﷺ said, "O you people of the ship! You will have (the reward of) two migrations."  

عَنْ أَبِي مُوسَى ؓ بَلَغَنَا مَخْرَجُ النَّبِيِّ ﷺ وَنَحْنُ بِالْيَمَنِ فَرَكِبْنَا سَفِينَةً فَأَلْقَتْنَا سَفِينَتُنَا إِلَى النَّجَاشِيِّ بِالْحَبَشَةِ فَوَافَقْنَا جَعْفَرَ بْنَ أَبِي طَالِبٍ فَأَقَمْنَا مَعَهُ حَتَّى قَدِمْنَا فَوَافَقْنَا النَّبِيَّ ﷺ حِينَ افْتَتَحَ خَيْبَرَ فَقَالَ النَّبِيُّ ﷺ لَكُمْ أَنْتُمْ يَا أَهْلَ السَّفِينَةِ هِجْرَتَانِ
