Full Sharh — Sahih al-Bukhari 678
حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ، قَالَ حَدَّثَنَا حُسَيْنٌ، عَنْ زَائِدَةَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، قَالَ حَدَّثَنِي أَبُو بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ مَرِضَ النَّبِيُّ صلى الله عليه وسلم فَاشْتَدَّ مَرَضُهُ فَقَالَ " مُرُوا أَبَا بَكْرٍ فَلْيُصَلِّ بِالنَّاسِ ". قَالَتْ عَائِشَةُ إِنَّهُ رَجُلٌ رَقِيقٌ، إِذَا قَامَ مَقَامَكَ لَمْ يَسْتَطِعْ أَنْ يُصَلِّيَ بِالنَّاسِ. قَالَ " مُرُوا أَبَا بَكْرٍ فَلْيُصَلِّ بِالنَّاسِ " فَعَادَتْ فَقَالَ " مُرِي أَبَا بَكْرٍ فَلْيُصَلِّ بِالنَّاسِ، فَإِنَّكُنَّ صَوَاحِبُ يُوسُفَ ". فَأَتَاهُ الرَّسُولُ فَصَلَّى بِالنَّاسِ فِي حَيَاةِ النَّبِيِّ صلى الله عليه وسلم.
English Translation
Narrated Abu Musa:"The Prophet (ﷺ) became sick and when his disease became aggravated, he said, "Tell Abu Bakr to lead the prayer." `Aisha said, "He is a softhearted man and would not be able to lead the prayer in your place." The Prophet (ﷺ) said again, "Tell Abu Bakr to lead the people in prayer." She repeated the same reply but he said, "Tell Abu Bakr to lead the people in prayer. You are the companions of Joseph." So the messenger went to Abu Bakr (with that order) and he led the people in prayer in the lifetime of the Prophet
