[Machine] There is no migration after the conquest, migration was only before the conquest when a person migrates for his religion to the Prophet ﷺ. But when the conquest occurred, a man can freely choose to become a follower of Allah, and no one can prevent him.  

البيهقي:١٧٧٧٦ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو بَكْرٍ أَحْمَدُ بْنُ الْحَسَنِ الْقَاضِي قَالَا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا إِبْرَاهِيمُ بْنُ مَرْزُوقٍ ثنا رَوْحٌ عَنِ ابْنِ جُرَيْجٍ أَخْبَرَنِي عَطَاءٌ أَنَّهُ جَاءَ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ ؓ مَعَ عُبَيْدِ بْنِ عُمَيْرٍ وَكَانَتْ مُجَاوِرَةً قَالَ فَقَالَ عُبَيْدٌ أَيْ هَنْتَاهُ أَسْأَلُكِ عَنِ الْهِجْرَةِ قَالَتْ

لَا هِجْرَةَ بَعْدَ الْفَتْحِ إِنَّمَا كَانَتِ الْهِجْرَةُ قَبْلَ الْفَتْحِ حَيْثُ يُهَاجِرُ الرَّجُلُ بِدِينِهِ إِلَى النَّبِيِّ ﷺ فَأَمَّا حِينَ كَانَ الْفَتْحُ حَيْثُ شَاءَ الرَّجُلُ عَبَدَ اللهَ لَا يُمْنَعُ
