[Machine] The Prophet ﷺ used to say, "O Allah," and he mentioned the supplication and said at the end, "And I seek refuge in You from being assassinated from beneath me." This means he sought protection from earthquakes. An-Nasai said: 'Ali ibn 'Abdul-'Aziz disagreed, saying that he did not know who this narration ties back to, but it is more likely to be traced back to his grandfather. Abu Nu'aim disagreed with him.  

كَانَ النَّبِيُّ ﷺ يَقُولُ «اللهُمَّ» وَذَكَرَ الدُّعَاءَ وَقَالَ فِي آخِرِهِ «وَأَعُوذُ بِكَ أَنْ أُغْتَالَ مِنْ تَحْتِي» يَعْنِي بِذَلِكَ الْخَسْفَ قَالَ النَّسَائِيُّ عَلِيُّ بْنُ عَبْدِ الْعَزِيزِ لَا أَعْرِفُهُ يَنْبَغِي أَنْ يَكُونَ نَسَبُهُ إِلَى جَدِّهِ خَالَفَهُ أَبُو نُعَيْمٍ  

"I heard the Messenger of Allah [SAW] say: 'Allahumma, inni a'udhu bi-'azamatika an ughtala min tahti (O Allah, I seek refuge in Your greatness from being swallowed up from beneath me.)'" (Using translation from Nasāʾī 5529)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «اللهُمَّ أَعُوذُ بِعَظَمَتِكَ أَنْ أُغْتَالَ مِنْ تَحْتِي» مُخْتَصَرٌ قَالَ جُبَيْرٌ وَهُوَ الْخَسْفُ قَالَ عُبَادَةُ فَلَا أَدْرِي قَوْلَ النَّبِيِّ ﷺ أَوْ جُبَيْرٍ
