Sahih al-Bukhari 4608

Narrated Aisha:

A necklace of mine was lost at Al-Baida' and we were on our way to Medina. The Prophet made his camel kneel down and dismounted and laid his head on my lap and slept. Abu Bakr came to me and hit me violently on the chest and said, "You have detained the people because of a necklace." I kept as motionless as a dead person because of the position of Allah's Apostle ;
(on my lap) although Abu Bakr had hurt me (with the slap). Then the Prophet woke up and it was the time for the morning (prayer). Water was sought, but in vain;
so the following Verse was revealed:-- "O you who believe! When you intend to offer prayer.." (5.6) Usaid bin Hudair said, "Allah has blessed the people for your sake, O the family of Abu Bakr. You are but a blessing for them."

حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي عَمْرٌو، أَنَّ عَبْدَ الرَّحْمَنِ بْنَ الْقَاسِمِ، حَدَّثَهُ عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ سَقَطَتْ قِلاَدَةٌ لِي بِالْبَيْدَاءِ وَنَحْنُ دَاخِلُونَ الْمَدِينَةَ، فَأَنَاخَ النَّبِيُّ ﷺ وَنَزَلَ، فَثَنَى رَأْسَهُ فِي حَجْرِي رَاقِدًا، أَقْبَلَ أَبُو بَكْرٍ فَلَكَزَنِي لَكْزَةً شَدِيدَةً وَقَالَ حَبَسْتِ النَّاسَ فِي قِلاَدَةٍ. فَبِي الْمَوْتُ لِمَكَانِ رَسُولِ اللَّهِ ﷺ وَقَدْ أَوْجَعَنِي، ثُمَّ إِنَّ النَّبِيَّ ﷺ اسْتَيْقَظَ وَحَضَرَتِ الصُّبْحُ فَالْتُمِسَ الْمَاءُ فَلَمْ يُوجَدْ فَنَزَلَتْ يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا قُمْتُمْ إِلَى الصَّلاَةِ الآيَةَ. فَقَالَ أُسَيْدُ بْنُ حُضَيْرٍ لَقَدْ بَارَكَ اللَّهُ لِلنَّاسِ فِيكُمْ يَا آلَ أَبِي بَكْرٍ، مَا أَنْتُمْ إِلاَّ بَرَكَةٌ لَهُمْ.
