[Machine] Salem, a servant of Abu Hudayfa, used to lead the migrants who immigrated to Medina in prayer, among them Umar and others from the migrants, because he was the most knowledgeable among them in the Quran.
«أَنَّ سَالِمًا مَوْلَى أَبِي حُذَيْفَةَ كَانَ يَؤُمُّ الْمُهَاجِرِينَ الَّذِينَ هَاجَرُوا إِلَى الْمَدِينَةِ فِيهِمْ عُمَرُ وَغَيْرُهُ مِنَ الْمُهَاجِرِينَ لِأَنَّهُ كَانَ أَكْثَرَهُمْ قُرْآنًا»
