"The Prophet [SAW] used to say: 'Allahumma (O Allah,)' and he mentioned the supplication, and said at the end, 'A'udhu bika an ughtala min tahti (and I seek refuge with You from being swallowed up from beneath me.)'"
كَانَ النَّبِيُّ ﷺ يَقُولُ اللَّهُمَّ فَذَكَرَ الدُّعَاءَ وَقَالَ فِي آخِرِهِ أَعُوذُ بِكَ أَنْ أُغْتَالَ مِنْ تَحْتِي يَعْنِي بِذَلِكَ الْخَسْفَ
[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.
