Sahih al-Bukhari 1376
Narrated Musa bin `Uqba:
(From the daughter of Khalid bin Sa id bin Al-`Asi) who said that she had heard the Prophet (ﷺ) seeking 
refuge with Allah from the punishment in the grave.
حَدَّثَنَا مُعَلًّى، حَدَّثَنَا وُهَيْبٌ، عَنْ مُوسَى بْنِ عُقْبَةَ، قَالَ حَدَّثَتْنِي ابْنَةُ خَالِدِ بْنِ سَعِيدِ بْنِ الْعَاصِ، أَنَّهَا سَمِعَتِ النَّبِيَّ صلى الله عليه وسلم وَهُوَ يَتَعَوَّذُ مِنْ عَذَابِ الْقَبْرِ‏.‏
