To seek refuge 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.
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.
