Sahih al-Bukhari 601
Narrated `Abdullah bin `Umar:
The Prophet (ﷺ) prayed one of the `Isha' prayer in his last days and after finishing it with Taslim, he stood 
up and said, "Do you realize (the importance of) this night? Nobody present on the 
surface of the earth tonight would be living after the completion of one hundred years from this 
night." 
The people made a mistake in grasping the meaning of this statement of Allah's Messenger (ﷺ) and they 
indulged in those things which are said about these narrators (i.e. some said that the Day of 
Resurrection will be established after 100 years etc.) But the Prophet (ﷺ) said, "Nobody present on the 
surface of earth tonight would be living after the completion of 100 years from this night"; he meant 
"When that century (people of that century) would pass away."
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ بْنِ عُمَرَ، وَأَبُو بَكْرِ بْنُ أَبِي حَثْمَةَ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ صَلَّى النَّبِيُّ صلى الله عليه وسلم صَلاَةَ الْعِشَاءِ فِي آخِرِ حَيَاتِهِ، فَلَمَّا سَلَّمَ قَامَ النَّبِيُّ صلى الله عليه وسلم فَقَالَ ‏"‏ أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ رَأْسَ مِائَةٍ لاَ يَبْقَى مِمَّنْ هُوَ الْيَوْمَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ ‏"‏‏.‏ فَوَهِلَ النَّاسُ فِي مَقَالَةِ رَسُولِ اللَّهِ ـ عَلَيْهِ السَّلاَمُ ـ إِلَى مَا يَتَحَدَّثُونَ مِنْ هَذِهِ الأَحَادِيثِ عَنْ مِائَةِ سَنَةٍ، وَإِنَّمَا قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ يَبْقَى مِمَّنْ هُوَ الْيَوْمَ عَلَى ظَهْرِ الأَرْضِ ‏"‏ يُرِيدُ بِذَلِكَ أَنَّهَا تَخْرِمُ ذَلِكَ الْقَرْنَ‏.‏
