"The Messenger of Allah ﷺ has been delayed (there) and the time for prayer has come, will you lead the people in prayer?" Abu Bakr said: 'Yes, if you wish.' Bilal said the Iqamah and Abu Bakr went forward and said the Takbir for the people. Then the Messenger of Allah ﷺ came, passing through the rows (of praying people) and stood in the (first) row and the people started clapping. Abu Bakr would never glance sideways in his prayer but when the people clapped so much he looked back and ﷺMessenger of Allah ﷺ. The Messenger of Allah ﷺ gestured to him to carry on praying. Aha Bakr raised his hands praising Allah the Mighty and Sublime, and retreated till he reached the (first) row. Then the Messenger ofAllah ﷺ went forward and led the people in the prayer. When he completed the prayer he turned to face the people and said: '0 people, why did you start clapping when something unusual happened to you in the prayer? Clapping is only for women. So whoever among you comes across something in the prayer should say: 'Subhan Allah' for there is none who will not turn round when they hear him saying Subhan Allah. 0 Abu Bakr! What prevented you from leading the people in the prayer when I gestured to you to do so?' Abu Bakr replied: 'It is not fitting for the son of Abu Quhafah to lead the prayer in the presence of the Messenger of Allah ﷺ.'" (Using translation from Nasāʾī 784)
خَرَجَ رَسُولُ اللهِ ﷺ إِلَى بَنِي عَمْرِو بْنِ عَوْفٍ فَحَضَرَتِ الصَّلَاةُ فَجَاءَ بِلَالٌ إِلَى أَبِي بَكْرٍ فَقَالَ يَا أَبَا بَكْرٍ إِنَّ الصَّلَاةَ قَدْ حَانَتْ وَحُبِسَ رَسُولُ اللهِ ﷺ فَتَؤُمُّ النَّاسَ؟ قَالَ إِنْ شِئْتَ فَأَقَامَ بِلَالٌ الصَّلَاةَ فَتَقَدَّمَ أَبُو بَكْرٍ فَجَاءَ رَسُولُ اللهِ ﷺ فَأَخَذَ النَّاسُ فِي التَّصْفِيحِ وَكَانَ أَبُو بَكْرٍ ؓ لَا يَلْتَفِتُ فِي صَلَاتِهِ فَلَمَّا أَكْثَرَ النَّاسُ الْتَفَتَ فَإِذَا بِرَسُولِ اللهِ ﷺ فِي الصَّفِّ فَأَشَارَ النَّبِيُّ ﷺ فَرَفَعَ أَبُو بَكْرٍ يَدَهُ فَحَمِدَ اللهَ ثُمَّ رَجَعَ أَبُو بَكْرٍ الْقَهْقَرَى وَرَاءَهُ حَتَّى رَجَعَ فِي الصَّفِّ فَتَقَدَّمَ رَسُولُ اللهِ ﷺ فَصَلَّى بِالنَّاسِ فَلَمَّا فَرَغَ أَقْبَلَ عَلَى النَّاسِ فَقَالَ أَيُّهَا النَّاسُ مَا لَكُمْ حِينَ نَابَكُمْ شَيْءٌ فِي الصَّلَاةِ أَخَذْتُمْ بِالتَّصْفِيحِ إِنَّمَا التَّصْفِيحُ لِلنِّسَاءِ فَمَنْ نَابَهُ شَيْءٌ فِي صَلَاتِهِ فَلْيَقُلْ سُبْحَانَ اللهِ فَإِنَّهُ لَا يَسْمَعُهُ أَحَدٌ إِلَّا الْتَفَتَ إِلَيْهِ يَا أَبَا بَكْرٍ مَا مَنَعَكَ أَنْ تُصَلِّيَ حِينَ أَشَرْتُ إِلَيْكَ؟ قَالَ مَا كَانَ يَنْبَغِي لِابْنِ أَبِي قُحَافَةَ أَنْ يُصَلِّيَ بَيْنَ يَدَيْ رَسُولِ اللهِ ﷺ
