سنن أبي داود#816Hasanحَدَّثَنَا 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 .
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
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Our source also lists this ruling under Muhammad Muhyi Al-Din Abdul Hamid, the editor of the printed edition it was taken from. It is al-Albani's ruling printed again, so it is counted once.
