Sahih Muslim Book - 4, Hadith - 949

حَدَّثَنِي يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَهَبَ إِلَى بَنِي عَمْرِو بْنِ عَوْفٍ لِيُصْلِحَ بَيْنَهُمْ فَحَانَتْ الصَّلَاةُ فَجَاءَ الْمُؤَذِّنُ إِلَى أَبِي بَكْرٍ فَقَالَ أَتُصَلِّي بِالنَّاسِ فَأُقِيمُ قَالَ نَعَمْ قَالَ فَصَلَّى أَبُو بَكْرٍ فَجَاءَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَالنَّاسُ فِي الصَّلَاةِ فَتَخَلَّصَ حَتَّى وَقَفَ فِي الصَّفِّ فَصَفَّقَ النَّاسُ وَكَانَ أَبُو بَكْرٍ لَا يَلْتَفِتُ فِي الصَّلَاةِ فَلَمَّا أَكْثَرَ النَّاسُ التَّصْفِيقَ الْتَفَتَ فَرَأَى رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَشَارَ إِلَيْهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ امْكُثْ مَكَانَكَ فَرَفَعَ أَبُو بَكْرٍ يَدَيْهِ فَحَمِدَ اللَّهَ عَزَّ وَجَلَّ عَلَى مَا أَمَرَهُ بِهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ ذَلِكَ ثُمَّ اسْتَأْخَرَ أَبُو بَكْرٍ حَتَّى اسْتَوَى فِي الصَّفِّ وَتَقَدَّمَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَصَلَّى ثُمَّ انْصَرَفَ فَقَالَ يَا أَبَا بَكْرٍ مَا مَنَعَكَ أَنْ تَثْبُتَ إِذْ أَمَرْتُكَ قَالَ أَبُو بَكْرٍ مَا كَانَ لِابْنِ أَبِي قُحَافَةَ أَنْ يُصَلِّيَ بَيْنَ يَدَيْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا لِي رَأَيْتُكُمْ أَكْثَرْتُمْ التَّصْفِيقَ مَنْ نَابَهُ شَيْءٌ فِي صَلَاتِهِ فَلْيُسَبِّحْ فَإِنَّهُ إِذَا سَبَّحَ الْتُفِتَ إِلَيْهِ وَإِنَّمَا التَّصْفِيحُ لِلنِّسَاءِ.

It was narrated from Sahl bin Sa'd As-Sa'idi that the Messenger of Allah (s.a.w) went to Banu 'Amr bin 'Awf to resolve a dispute among them. The time for prayer became due, and the Mu'adhdhin came to Abu Bakr and said: "Will you lead the people in prayer, and I will say the Iqamah?" He said: "Yes." So Abu Bakr led the people in prayer, then the Messenger of Allah (s.a.w) came while the people were still praying. He came and stood in the row, and the people started clapping. Abu Bakr would not pay attention to anything while he was praying, but when the people's clapping increased, he turned around and saw the Messenger of Allah (s.a.w). The Messenger of Allah (s.a.w) gestured to him to stay where he was. Abu Bakr raised his hands, praising Allah, the Mighty and Sublime, for the command of the Messenger of Allah (s.a.w). Then Abu Bakr moved backwards until he was level with the row, and the Prophet (s.a.w) came forward and (continued the) prayers. Then when he had finished he said: "O Abu Bakr, what prevented you from staying put when I told you to?" Abu Bakr said: "It is not for the son of Abu Quhafah to pray in front of the Messenger of Allah (s.a.w)." The Messenger of Allah (s.a.w) said: "Why did I see you clapping so much? If something happens to a man when he is in prayers, let him say: 'Subhan-Allah,' for if he says 'Subhan-Allah' it will be noted. Clapping is only for women."
