[Machine] Abdullah, we used to greet the Prophet ﷺ and he would respond to us during prayer. But when we came from the land of Abyssinia, I greeted him and he didn't reply. He grabbed me and held me tightly until he finished praying. I said to him, "You used to respond to us." He ﷺ said, "Indeed, Allah speaks whatever He wills, and He has ordained that you do not speak during prayer."
عَبْدُ اللَّهِ كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ ﷺ فَيَرُدُّ عَلَيْنَا يَعْنِي فِي الصَّلَاةِ فَلَمَّا أَنْ جِئْنَا مِنْ أَرْضِ الْحَبَشَةِ سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَأَخَذَنِي مَا قَرُبَ وَ بَعُدَ فَجَلَسْتُ حَتَّى قَضَى الصَّلَاةَ قُلْتُ لَهُ إِنَّكَ كُنْتَ تَرُدُّ عَلَيْنَا فَقَالَ ﷺ «إِنَّ اللَّهَ يُحْدِثُ مَا شَاءَ وَقَدْ أَحْدَثَ مِنْ أَمْرِهِ قَضَاءً أَنْ لَا تَكَلَّمُوا فِي الصَّلَاةِ»
