حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، عَنْ مُجَاشِعِ بْنِ مَسْعُودٍ، قَالَ جَاءَ مُجَاشِعٌ بِأَخِيهِ مُجَالِدِ بْنِ مَسْعُودٍ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ هَذَا مُجَالِدٌ يُبَايِعُكَ عَلَى الْهِجْرَةِ. فَقَالَ " لاَ هِجْرَةَ بَعْدَ فَتْحِ مَكَّةَ، وَلَكِنْ أُبَايِعُهُ عَلَى الإِسْلاَمِ ".
