صحيح البخاري#389Sahihأَخْبَرَنَا الصَّلْتُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا مَهْدِيٌّ، عَنْ وَاصِلٍ، عَنْ أَبِي وَائِلٍ، عَنْ حُذَيْفَةَ، رَأَى رَجُلاً لاَ يُتِمُّ رُكُوعَهُ وَلاَ سُجُودَهُ، فَلَمَّا قَضَى صَلاَتَهُ قَالَ لَهُ حُذَيْفَةُ مَا صَلَّيْتَ ـ قَالَ وَأَحْسِبُهُ قَالَ ـ لَوْ مُتَّ مُتَّ عَلَى غَيْرِ سُنَّةِ مُحَمَّدٍ صلى الله عليه وسلم.

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:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
