“When the fierce battles take place, Allah will send a troop of freed slaves who will be the best Arab horsemen and the best armed, with whom Allah will support His religion.” (Using translation from Ibn Mājah 4090)
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِذَا وَقَعَتِ الْمَلَاحِمُ خَرَجَ بَعْثٌ مِنَ الْمَوَالِي مِنْ دِمَشْقَ هُمْ أَكْرَمُ الْعَرَبِ فَرَسًا وَأَجْوَدُهُ سِلَاحًا يُؤَيِّدُ اللَّهُ بِهُمُ الدِّينَ»
