عَنْ يَحْيَى بْنِ إِسْحَاقَ عَنْ مُجَاشِعِ بْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ أَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِابْنِ أَخٍ لَهُ يُبَايِعُهُ عَلَى الْهِجْرَةِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا بَلْ يُبَايِعُ عَلَى الْإِسْلَامِ فَإِنَّهُ لَا هِجْرَةَ بَعْدَ الْفَتْحِ وَيَكُونُ مِنَ التَّابِعِينَ بِإِحْسَانٍ
It is narrated from Sayyiduna Mujashi‘ bin Mas‘ud (may Allah be pleased with him) that he brought his nephew to the Noble Prophet (peace and blessings be upon him) so that the Prophet (peace and blessings be upon him) would take his pledge of allegiance for migration. But the Prophet (peace and blessings be upon him) said: No, now the pledge will be for Islam. After the conquest of Makkah, there is no migration. Now this person will be among those who follow with excellence.
