[Machine] "He greeted a man while he was praying, and the man responded to him with words. He said, 'When someone greets you while you are praying, do not speak, but instead motion with your hand.'"
أَنَّهُ سَلَّمَ عَلَى رَجُلٍ وَهُوَ يُصَلِّي فَرَدَّ عَلَيْهِ الرَّجُلُ كَلَامًا فَقَالَ إِذَا سُلِّمَ عَلَى أَحَدِكُمْ وَهُوَ يُصَلِّي فَلَا يَتَكَلَّمْ وَلَكِنْ يُشِيرُ بِيَدِهِ
Yahya related to me from Malik from Nafi that Abdullah ibn Umar passed by a man who was praying and said, "Peace be upon you," and the man replied to him. Abdullah ibn Umar returned to him and said, "When someone says, 'Peace be upon you' to you while you are praying do not reply, but give a signal with your hand."
أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ مَرَّ عَلَى رَجُلٍ وَهُوَ يُصَلِّي فَسَلَّمَ عَلَيْهِ فَرَدَّ الرَّجُلُ كَلاَمًا فَرَجَعَ إِلَيْهِ عَبْدُ اللَّهِ بْنُ عُمَرَ فَقَالَ لَهُ إِذَا سُلِّمَ عَلَى أَحَدِكُمْ وَهُوَ يُصَلِّي فَلاَ يَتَكَلَّمْ وَلْيُشِرْ بِيَدِهِ
