صحيح البخاري#7247Sahihحَدَّثَنَا مُسَدَّدٌ، عَنْ يَحْيَى، عَنِ التَّيْمِيِّ، عَنْ أَبِي عُثْمَانَ، عَنِ ابْنِ مَسْعُودٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَمْنَعَنَّ أَحَدَكُمْ أَذَانُ بِلاَلٍ مِنْ سَحُورِهِ، فَإِنَّهُ يُؤَذِّنُ ـ أَوْ قَالَ يُنَادِي ـ لِيَرْجِعَ قَائِمَكُمْ، وَيُنَبِّهَ نَائِمَكُمْ، وَلَيْسَ الْفَجْرُ أَنْ يَقُولَ هَكَذَا ـ وَجَمَعَ يَحْيَى كَفَّيْهِ ـ حَتَّى يَقُولَ هَكَذَا ". وَمَدَّ يَحْيَى إِصْبَعَيْهِ السَّبَّابَتَيْنِ.
Narrated Ibn Mas`ud:Allah's Messenger (ﷺ) said, "The (call for prayer) Adhan of Bilal should not stop anyone of you from taking his Suhur for he pronounces the Adhan in order that whoever among you is praying the night prayer, may return (to eat his Suhur) and whoever among you is sleeping, may get up, for it is not yet dawn (when it is like this)." (Yahya, the sub-narrator stretched his two index fingers side ways)
Scholarly Authentication
The label above is the grade most of these scholars gave — 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. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
