It was narrated from 'Abdullah bin 'Umar, that he said:

"The Messenger of Allahﷺ led us in Salat one night for Salat Al-'Isha' during the end of his life. When he said the Taslim he stood and said: 'Do you see this night of yours, upon the head of one hundred years from it there shall not remain anyone who is upon the surface of the earth today.' Ibn 'Umar said: 'So, people misunderstood the saying of the Messenger of Allahﷺ, in what they say based on these Ahadith about one hundred years. The Messenger of Allahﷺ only said: 'There shall not remain anyone who is upon the surface today.' Meaning, that generation would end."

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، وَأَبِي، بَكْرِ بْنِ سُلَيْمَانَ وَهُوَ ابْنُ أَبِي حَثْمَةَ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ ذَاتَ لَيْلَةٍ صَلاَةَ الْعِشَاءِ فِي آخِرِ حَيَاتِهِ فَلَمَّا سَلَّمَ قَالَ " أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ عَلَى رَأْسِ مِائَةِ سَنَةٍ مِنْهَا لاَ يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ " . قَالَ ابْنُ عُمَرَ فَوَهَلَ النَّاسُ فِي مَقَالَةِ رَسُولِ اللَّهِ ﷺ تِلْكَ فِيمَا يَتَحَدَّثُونَهُ مِنْ هَذِهِ الأَحَادِيثِ عَنْ مِائَةِ سَنَةٍ وَإِنَّمَا قَالَ رَسُولُ اللَّهِ ﷺ " لاَ يَبْقَى مِمَّنْ هُوَ الْيَوْمَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ " . يُرِيدُ بِذَلِكَ أَنْ يَنْخَرِمَ ذَلِكَ الْقَرْنُ .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ صَحِيحٌ .
