Sahih Muslim 421 a
Sahl b. Sa'd al-Sa'idi reported:
The Messenger of Allah (ﷺ) went to the tribe of Bani Amr b. Auf in order to bring reconciliation amongst (its members), and It was a time of prayer. The Mu'adhdhin came to Abu Bakr and said: Would you lead the prayer in case I recite takbir (tahrima, with which the prayer begins)? He (Abu Bakr) said: Yes. He (the narrator) said: He (Abu Bakr) started (leading) the prayer. The people were engaged in observing prayer when the Messenger of Allah (ﷺ) happened to come there and made his way (through the people) till he stood in a row. The people began to clap (their hands), but Abu Bakr paid no heed (to it) in prayer. When the people clapped more vigorously, he (Abu Bakr) then paid heed and saw the Messenger of Allah (ﷺ) there. (He was about to withdraw when) the Messenger of Allah (ﷺ) signed to him to keep standing at his place. Abu Bakr lifted his hands and praised Allah for what the Messenger of Allah (ﷺ) had commanded him and then Abu Bakr withdrew himself till he stood in the midst of the row and the Messenger of Allah (ﷺ) stepped forward and led the prayer. When (the prayer) was over, he (the Holy Prophet) said: 0 Abu Bakr, what prevented you from standing (at that place) as I ordered you to do? Abu Bakr said: It does not become the son of Abu Quhafa to lead prayer before the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) said (to the people) around him: What is it that I saw you clapping so vigorously? (Behold) when anything happens in prayer, say: Subha Allah, for when you would utter it, it would attract the attention, while clapping of hands is meant for women.
حَدَّثَنِي يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم ذَهَبَ إِلَى بَنِي عَمْرِو بْنِ عَوْفٍ لِيُصْلِحَ بَيْنَهُمْ فَحَانَتِ الصَّلاَةُ فَجَاءَ الْمُؤَذِّنُ إِلَى أَبِي بَكْرٍ فَقَالَ أَتُصَلِّي بِالنَّاسِ فَأُقِيمُ قَالَ نَعَمْ ‏.‏ قَالَ فَصَلَّى أَبُو بَكْرٍ فَجَاءَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَالنَّاسُ فِي الصَّلاَةِ فَتَخَلَّصَ حَتَّى وَقَفَ فِي الصَّفِّ فَصَفَّقَ النَّاسُ - وَكَانَ أَبُو بَكْرٍ لاَ يَلْتَفِتُ فِي الصَّلاَةِ - فَلَمَّا أَكْثَرَ النَّاسُ التَّصْفِيقَ الْتَفَتَ فَرَأَى رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَشَارَ إِلَيْهِ رَسُولُ اللَّهِ صلى الله عليه وسلم أَنِ امْكُثْ مَكَانَكَ فَرَفَعَ أَبُو بَكْرٍ يَدَيْهِ فَحَمِدَ اللَّهَ عَزَّ وَجَلَّ عَلَى مَا أَمَرَهُ بِهِ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ ذَلِكَ ثُمَّ اسْتَأْخَرَ أَبُو بَكْرٍ حَتَّى اسْتَوَى فِي الصَّفِّ وَتَقَدَّمَ النَّبِيُّ صلى الله عليه وسلم فَصَلَّى ثُمَّ انْصَرَفَ فَقَالَ ‏"‏ يَا أَبَا بَكْرٍ مَا مَنَعَكَ أَنْ تَثْبُتَ إِذْ أَمَرْتُكَ ‏"‏ ‏.‏ قَالَ أَبُو بَكْرٍ مَا كَانَ لاِبْنِ أَبِي قُحَافَةَ أَنْ يُصَلِّيَ بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا لِي رَأَيْتُكُمْ أَكْثَرْتُمُ التَّصْفِيقَ مَنْ نَابَهُ شَىْءٌ فِي صَلاَتِهِ فَلْيُسَبِّحْ فَإِنَّهُ إِذَا سَبَّحَ الْتُفِتَ إِلَيْهِ وَإِنَّمَا التَّصْفِيحُ لِلنِّسَاءِ ‏"‏ ‏.‏
