صحيح البخاري#564Sahihحَدَّثَنَا عَبْدَانُ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ، قَالَ أَخْبَرَنَا يُونُسُ، عَنِ الزُّهْرِيِّ، قَالَ سَالِمٌ أَخْبَرَنِي عَبْدُ اللَّهِ، قَالَ صَلَّى لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم لَيْلَةً صَلاَةَ الْعِشَاءِ ـ وَهْىَ الَّتِي يَدْعُو النَّاسُ الْعَتَمَةَ ـ ثُمَّ انْصَرَفَ فَأَقْبَلَ عَلَيْنَا فَقَالَ " أَرَأَيْتُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ رَأْسَ مِائَةِ سَنَةٍ مِنْهَا لاَ يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ ".
Narrated `Abdullah:"One night Allah's Messenger (ﷺ) led us in the `Isha' prayer and that is the one called Al-`Atma [??] by the people. After the completion of the prayer, he faced us and said, "Do you know the importance of this night? Nobody present on the surface of the earth tonight will be living after one hundred years from this night." (See Hadith No)

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