Narrated Mu'adh ibn Abdullah al-Juhani: A man of Juhaynah told him that he had heard the Prophet (ﷺ) reciting "When the earth is shaken" (Surah 99) in both rak'ahs of the morning prayer. But I do not know whether he had forgotten, or whether he recited it on purpose.

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، عَنِ ابْنِ أَبِي هِلاَلٍ، عَنْ مُعَاذِ بْنِ عَبْدِ اللَّهِ الْجُهَنِيِّ، أَنَّ رَجُلاً، مِنْ جُهَيْنَةَ أَخْبَرَهُ أَنَّهُ سَمِعَ النَّبِيَّ صلى الله عليه وسلم يَقْرَأُ فِي الصُّبْحِ ‏{‏ إِذَا زُلْزِلَتِ الأَرْضُ ‏}‏ فِي الرَّكْعَتَيْنِ كِلْتَيْهِمَا فَلاَ أَدْرِي أَنَسِيَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَمْ قَرَأَ ذَلِكَ عَمْدًا ‏.‏
