Sahih Muslim 420Book 4, Hadith 110
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حُسَيْنُ بْنُ عَلِيٍّ، عَنْ زَائِدَةَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ مَرِضَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَاشْتَدَّ مَرَضُهُ فَقَالَ " مُرُوا أَبَا بَكْرٍ فَلْيُصَلِّ بِالنَّاسِ " . فَقَالَتْ عَائِشَةُ يَا رَسُولَ اللَّهِ إِنَّ أَبَا بَكْرٍ رَجُلٌ رَقِيقٌ مَتَى يَقُمْ مَقَامَكَ لاَ يَسْتَطِعْ أَنْ يُصَلِّيَ بِالنَّاسِ فَقَالَ " مُرِي أَبَا بَكْرٍ فَلْيُصَلِّ بِالنَّاسِ فَإِنَّكُنَّ صَوَاحِبُ يُوسُفَ " . قَالَ فَصَلَّى بِهِمْ أَبُو بَكْرٍ حَيَاةَ رَسُولِ اللَّهِ صلى الله عليه وسلم .
When the Messenger of Allah (ﷺ) became ill and illness became serious he ordered Abu Bakr to lead the people in prayer. Upon this 'A'isha said: Messenger of Allah, Abd Bakr is a man of tenderly feelings: when he would stand in your place (he would be so much overwhelmed -by grief that) he would not be able to lead the people in prayer. He (the Holy Prophet) said: You order Abu Bakr to lead the people in prayer, and added: You are like the female companions of Yusuf. So Abu Bakr led the prayer (during this period of illness) in the life of the Messenger of Allah (ﷺ).
