Returning the salams with a gesture when praying

It was narrated that Suhaib, the Companion of the Messenger of Allah (ﷺ) said:

"I passed by the Messenger of Allah (ﷺ) when he was praying, and greeted him with Salam. He returned my greeting with a gesture, or maybe it was just with his finger."

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ بُكَيْرٍ، عَنْ نَابِلٍ، صَاحِبِ الْعَبَاءِ عَنِ ابْنِ عُمَرَ، عَنْ صُهَيْبٍ، صَاحِبِ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ مَرَرْتُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَرَدَّ عَلَىَّ إِشَارَةً وَلاَ أَعْلَمُ إِلاَّ أَنَّهُ قَالَ بِإِصْبَعِهِ ‏.‏

It was narrated that Zaid bin Aslam said:

"Ibn 'Umar said: The Prophet (ﷺ) entered the Masjid of Quba' to pray there, then some men came in and greeted him with Salam. I asked Suhaib, who was with him: 'What did the Messenger of Allah (ﷺ) do when he was greeted?' He said: 'He used to gesture with his hand.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ الْمَكِّيُّ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ زَيْدِ بْنِ أَسْلَمَ، قَالَ قَالَ ابْنُ عُمَرَ دَخَلَ النَّبِيُّ صلى الله عليه وسلم مَسْجِدَ قُبَاءَ لِيُصَلِّيَ فِيهِ فَدَخَلَ عَلَيْهِ رِجَالٌ يُسَلِّمُونَ عَلَيْهِ فَسَأَلْتُ صُهَيْبًا وَكَانَ مَعَهُ كَيْفَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَصْنَعُ إِذَا سُلِّمَ عَلَيْهِ قَالَ كَانَ يُشِيرُ بِيَدِهِ ‏.‏

It was narrated from 'Ammar bin Yasir that:

He greeted the Messenger of Allah (ﷺ) with the Salam when he was praying, and he returned the greeting.

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا وَهْبٌ، - يَعْنِي ابْنَ جَرِيرٍ - قَالَ حَدَّثَنَا أَبِي، عَنْ قَيْسِ بْنِ سَعْدٍ، عَنْ عَطَاءٍ، عَنْ مُحَمَّدِ بْنِ عَلِيٍّ، عَنْ عَمَّارِ بْنِ يَاسِرٍ، أَنَّهُ سَلَّمَ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ يُصَلِّي فَرَدَّ عَلَيْهِ ‏.‏

It was narrated that Jabir said:

"The Messenger of Allah (ﷺ) sent me on an errand then I came back to him while he was praying. I greeted him with the salam and he gestured to me. When he finished he called me and said: 'You greeted me with Salam just now and I was praying.' And he was facing toward the east that day."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ بَعَثَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم لِحَاجَةٍ ثُمَّ أَدْرَكْتُهُ وَهُوَ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَأَشَارَ إِلَىَّ فَلَمَّا فَرَغَ دَعَانِي فَقَالَ ‏

‏ إِنَّكَ سَلَّمْتَ عَلَىَّ آنِفًا وَأَنَا أُصَلِّي ‏

‏ ‏.‏ وَإِنَّمَا هُوَ مُوَجَّهٌ يَوْمَئِذٍ إِلَى الْمَشْرِقِ

It was narrated that Jabir said:

"The Messenger of Allah (ﷺ) sent me on an errand, then I came back to him while he was facing the east or the west. I greeted him with salam and he gestured to me. Then when he finished he called me and said: "O Jabir!" So I came and said: "O Messenger of Allah, I greeted you with Salam but you did not answer." He said: 'I was praying.'

أَخْبَرَنَا مُحَمَّدُ بْنُ هَاشِمٍ الْبَعْلَبَكِّيُّ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ شُعَيْبِ بْنِ شَابُورٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، قَالَ أَخْبَرَنِي أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ بَعَثَنِي النَّبِيُّ صلى الله عليه وسلم فَأَتَيْتُهُ وَهُوَ يَسِيرُ مُشَرِّقًا أَوْ مُغَرِّبًا فَسَلَّمْتُ عَلَيْهِ فَأَشَارَ بِيَدِهِ ثُمَّ سَلَّمْتُ عَلَيْهِ فَأَشَارَ بِيَدِهِ فَانْصَرَفْتُ فَنَادَانِي ‏"‏ يَا جَابِرُ ‏"‏ ‏.‏ فَنَادَانِي النَّاسُ يَا جَابِرُ ‏.‏ فَأَتَيْتُهُ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي سَلَّمْتُ عَلَيْكَ فَلَمْ تَرُدَّ عَلَىَّ ‏.‏ فَقَالَ ‏"‏ إِنِّي كُنْتُ أُصَلِّي ‏"‏ ‏.‏
