Sahih al-Bukhari, Hadith 5666 ⓘ

Narrated Al-Qasim bin Muhammad: `Aisha, (complaining of headache) said, "Oh, my head"! Allah's Messenger said, "I wish that had happened while I was still living, for then I would ask Allah's Forgiveness for you and invoke Allah for you." Aisha said, "Wa thuklayah! By Allah, I think you want me to die; and If this should happen, you would spend the last part of the day sleeping with one of your wives!" The Prophet said, "Nay, I should say, 'Oh my head!' I felt like sending for Abu Bakr and his son, and appoint him as my successor lest some people claimed something or some others wished something, but then I said (to myself), 'Allah would not allow it to be otherwise, and the Muslims would prevent it to be otherwise".

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَبُو زَكَرِيَّاءَ، أَخْبَرَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، قَالَ سَمِعْتُ الْقَاسِمَ بْنَ مُحَمَّدٍ، قَالَ قَالَتْ عَائِشَةُ وَارَأْسَاهْ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ذَاكِ لَوْ كَانَ وَأَنَا حَىٌّ، فَأَسْتَغْفِرُ لَكِ وَأَدْعُو لَكِ ‏"‏‏.‏ فَقَالَتْ عَائِشَةُ وَاثُكْلِيَاهْ، وَاللَّهِ إِنِّي لأَظُنُّكَ تُحِبُّ مَوْتِي، وَلَوْ كَانَ ذَاكَ لَظَلِلْتَ آخِرَ يَوْمِكَ مُعَرِّسًا بِبَعْضِ أَزْوَاجِكَ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ بَلْ أَنَا وَارَأْسَاهْ لَقَدْ هَمَمْتُ أَوْ أَرَدْتُ أَنْ أُرْسِلَ إِلَى أَبِي بَكْرٍ وَابْنِهِ، وَأَعْهَدَ أَنْ يَقُولَ الْقَائِلُونَ أَوْ يَتَمَنَّى الْمُتَمَنُّونَ، ثُمَّ قُلْتُ يَأْبَى اللَّهُ وَيَدْفَعُ الْمُؤْمِنُونَ، أَوْ يَدْفَعُ اللَّهُ وَيَأْبَى الْمُؤْمِنُونَ ‏"‏‏.‏
