Sahih Bukhari Volume 1, Book 10, Hadith 716

حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ فِي مَرَضِهِ ‏"‏ مُرُوا أَبَا بَكْرٍ يُصَلِّي بِالنَّاسِ ‏"‏‏.‏ قَالَتْ عَائِشَةُ قُلْتُ إِنَّ أَبَا بَكْرٍ إِذَا قَامَ فِي مَقَامِكَ لَمْ يُسْمِعِ النَّاسَ مِنَ الْبُكَاءِ، فَمُرْ عُمَرَ فَلْيُصَلِّ‏.‏ فَقَالَ ‏"‏ مُرُوا أَبَا بَكْرٍ فَلْيُصَلِّ لِلنَّاسِ ‏"‏‏.‏ قَالَتْ عَائِشَةُ لِحَفْصَةَ قُولِي لَهُ إِنَّ أَبَا بَكْرٍ إِذَا قَامَ فِي مَقَامِكَ لَمْ يُسْمِعِ النَّاسَ مِنَ الْبُكَاءِ، فَمُرْ عُمَرَ فَلْيُصَلِّ لِلنَّاسِ‏.‏ فَفَعَلَتْ حَفْصَةُ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَهْ، إِنَّكُنَّ لأَنْتُنَّ صَوَاحِبُ يُوسُفَ، مُرُوا أَبَا بَكْرٍ فَلْيُصَلِّ لِلنَّاسِ ‏"‏‏.‏ قَالَتْ حَفْصَةُ لِعَائِشَةَ مَا كُنْتُ لأُصِيبَ مِنْكِ خَيْرًا‏

Narrated By 'Aisha : The mother of the faithful believers: Allah's Apostle in his last illness said, "Tell Abu Bakr to lead the people in the prayer." I said, "If Abu Bakr stood in your place, he would not be able to make the people hear him owing to his weeping. So please order 'Umar to lead the prayer." He said, "Tell Abu Bakr to lead the people in the prayer." I said to Hafsa, "Say to him, 'Abu Bakr is a soft-hearted man and if he stood in your place he would not be able to make the people hear him owing to his weeping. So order 'Umar to lead the people in the prayer.' " Hafsa did so but Allah's Apostle said, "Keep quiet. Verily you are the companions of (Prophet) Joseph. Tell Abu Bakr to lead the people in the prayer." Hafsa said to me, "I never got any good from you."
