سنن أبي داود#1149Hasanحَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ لَهِيعَةَ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُكَبِّرُ فِي الْفِطْرِ وَالأَضْحَى فِي الأُولَى سَبْعَ تَكْبِيرَاتٍ وَفِي الثَّانِيَةِ خَمْسًا .
Narrated Aisha, Ummul Mu'minin: The Messenger of Allah (ﷺ) would say the takbir (Allah is most great) seven times in the first rak'ah and five times in the second rak'ah on the day of the breaking of the fast and on the day of sacrifice (on the occasion of both the 'Id prayers, the two festivals)
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.
