[Machine] The Messenger of Allah ﷺ entered the Masjid of Bani Amr ibn Auf while it was the Quba Mosque where he used to pray. Then some men from the Ansar entered and greeted him. Ibn Umar said, "Suhaib also entered with them, so I asked him, 'How did the Messenger of Allah ﷺ respond when greeted while he was in prayer?' He said, 'He used to gesture with his hand.'"
دَخَلَ رَسُولُ اللَّهِ ﷺ مَسْجِدَ بَنِي عَمْرِو بْنِ عَوْفٍ وَهُوَ مَسْجِدُ قُبَاءَ يُصَلِّي فِيهِ فَدَخَلَ عَلَيْهِ رِجَالٌ مِنَ الْأَنْصَارِ يُسَلِّمُونَ عَلَيْهِ قَالَ ابْنُ عُمَرَ وَدَخَلَ مَعَهُمْ صُهَيْبٌ فَسَأَلْتُهُ كَيْفَ كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ إِذَا سُلِّمَ عَلَيْهِ وَهُوَ فِي الصَّلَاةِ؟ قَالَ «كَانَ يُشِيرُ بِيَدِهِ»
