[Machine] From the Prophet ﷺ he said, "There is no greeting or salaam in prayer." Ahmad ibn Hanbal said, "In my opinion, what he meant is that one should not say the salaam and then greet you. The man's hesitation in his prayer is to say the salaam while he is in doubt, as mentioned in my book." Abu Ali al-Rudhbari informed us that Abu Bakr ibn Dasa informed us that Abu Dawud narrated to us from Ahmad ibn Hanbal, who mentioned it with its chain of narration, except that he said, "There is no greeting or salaam in prayer." Ahmad ibn Hanbal meant that one should not say the salaam and then greet you. The man hesitates in his prayer and then leaves while he is in doubt. This wording is closer to the explanation of Ahmad ibn Hanbal. Abu Dawud said.  

عَنِ النَّبِيِّ ﷺ قَالَ لَا غِرَارَ فِي صَلَاةٍ وَلَا تَسْلِيمٍ قَالَ أَحْمَدُ بْنُ حَنْبَلٍ فِيمَا أَرَى أَنَّهُ أَرَادَ أَنْ لَا تُسَلِّمَ وَيُسَلَّمَ عَلَيْكَ وَتْغِرِيرُ الرَّجُلِ بِصَلَاتِهِ أَنْ يُسَلِّمَ وَهُوَ فِيهَا شَاكٌّ كَذَا فِي كِتَابِي وَأَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ أَبُو بَكْرِ بْنُ دَاسَةَ أنبأ أَبُو دَاوُدَ ثنا أَحْمَدُ بْنُ حَنْبَلٍ فَذَكَرَهُ بِإِسْنَادِهِ إِلَّا أَنَّهُ قَالَ لَا غِرَارَ فِي صَلَاةٍ وَلَا تَسْلِيمٍ قَالَ أَحْمَدُ بْنُ حَنْبَلٍ يَعْنِي فِيمَا أَرَى أَنْ لَا تُسَلِّمَ وَيُسَلَّمَ عَلَيْكَ وَيُغَرِّرُ الرَّجُلُ بِصَلَاتِهِ فَيَنْصَرِفُ وَهُوَ فِيهَا شَاكٌّ وَهَذَا اللَّفْظُ أَقْرَبُ إِلَى تَفْسِيرِ أَحْمَدَ بْنِ حَنْبَلٍ قَالَ أَبُو دَاوُدَ  

[Machine] Regarding prayer and sending greetings, all the past news that allows sending greetings to the one who prays and responding with a gesture, as it is better to follow and with Allah is the guidance.  

عَنِ الصَّلَاةِ وَالتَّسْلِيمِ جَمِيعًا وَالْأَخْبَارُ الَّتِي مَضَتْ تُبِيحُ التَّسْلِيمَ عَلَى الْمُصَلِّي وَالرَّدَّ بِالْإِشَارَةِ وَهِيَ أَوْلَى بِالِاتِّبَاعِ وَبِاللهِ التَّوْفِيقُ
