باب أَهْلُ الْعِلْمِ وَالْفَضْلِ أَحَقُّ بِالإِمَامَةِ
Sahih al-Bukhari 679

Narrated `Aisha:

the mother of the believers: Allah's Messenger (ﷺ) in his illness said, "Tell Abu Bakr to lead the people in prayer." I said to him, "If Abu Bakr stands in your place, the people would not hear him owing to his (excessive) weeping. So please order `Umar to lead the prayer." `Aisha added I said to Hafsa, "Say to him: If Abu Bakr should lead the people in the prayer in your place, the people would not be able to hear him owing to his weeping; so please, order `Umar to lead the prayer." Hafsa did so but Allah's Apostle said, "Keep quiet! You are verily the Companions of Joseph. Tell Abu Bakr to lead the people in the prayer. " Hafsa said to `Aisha, "I never got anything good from you."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ ـ رضى الله عنها ـ أَنَّهَا قَالَتْ إِنَّ 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 لِلنَّاسِ‏.‏ فَقَالَتْ عَائِشَةُ فَقُلْتُ 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 ‏"‏‏.‏ فَقَالَتْ حَفْصَةُ لِعَائِشَةَ مَا كُنْتُ لأُصِيبَ مِنْكِ خَيْرًا‏.‏
