[Machine] A man came and pledged allegiance to the Prophet ﷺ for migration, without realizing that he was a slave. Then, his master came looking for him, so the Prophet ﷺ said to him, "Buy him from me." So, he bought him for two black slaves. After that, the man did not pledge allegiance to anyone until another man asked him, "Are you a slave?"  

جَاءَ عَبْدٌ فَبَايَعَ النَّبِيَّ ﷺ عَلَى الْهِجْرَةِ وَلَمْ يَشْعُرْ أَنَّهُ عَبْدٌ فَجَاءَ سَيِّدُهُ يُرِيدُهُ فَقَالَ لَهُ النَّبِيُّ ﷺ بِعْنِيهِ فَاشْتَرَاهُ بِعَبْدَيْنِ أَسْوَدَيْنِ ثُمَّ لَمْ يُبَايِعْ أَحَدًا بَعْدُ حَتَّى يَسْأَلَهُ أَعَبْدٌ هُوَ؟
