Messenger of Allah ﷺ disliked to sleep before the ʿIsha' prayer and to talk after it.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَكْرَهُ النَّوْمَ قَبْلَ الْعِشَاءِ وَالْحَدِيثَ بَعْدَهَا  

Once the Prophet ﷺ led us in the ʿIsha' prayer during the last days of his life and after finishing it (the prayer) (with Taslim) he said: "Do you realize (the importance of) this night?" Nobody present on the surface of the earth tonight will be living after the completion of one hundred years from this night."  

صَلَّى بِنَا النَّبِيُّ ﷺ الْعِشَاءَ فِي آخِرِ حَيَاتِهِ فَلَمَّا سَلَّمَ قَامَ فَقَالَ أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ رَأْسَ مِائَةِ سَنَةٍ مِنْهَا لاَ يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ  

"One night Messenger of Allah ﷺ led us in the ʿIsha' prayer and that is the one called Al-ʿAtma [??] 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. 575).  

صَلَّى لَنَا رَسُولُ اللَّهِ ﷺ لَيْلَةً صَلاَةَ الْعِشَاءِ وَهْىَ الَّتِي يَدْعُو النَّاسُ الْعَتَمَةَ ثُمَّ انْصَرَفَ فَأَقْبَلَ عَلَيْنَا فَقَالَ أَرَأَيْتُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ رَأْسَ مِائَةِ سَنَةٍ مِنْهَا لاَ يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ  

The Prophet ﷺ prayed one of the ʿIsha' 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 Messenger of Allah 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."  

صَلَّى النَّبِيُّ ﷺ صَلاَةَ الْعِشَاءِ فِي آخِرِ حَيَاتِهِ فَلَمَّا سَلَّمَ قَامَ النَّبِيُّ ﷺ فَقَالَ أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ رَأْسَ مِائَةٍ لاَ يَبْقَى مِمَّنْ هُوَ الْيَوْمَ عَلَى ظَهْرِ الأَرْضِ أَحَدٌ فَوَهِلَ النَّاسُ فِي مَقَالَةِ رَسُولِ اللَّهِ عَلَيْهِ السَّلاَمُ إِلَى مَا يَتَحَدَّثُونَ مِنْ هَذِهِ الأَحَادِيثِ عَنْ مِائَةِ سَنَةٍ وَإِنَّمَا قَالَ النَّبِيُّ ﷺ لاَ يَبْقَى مِمَّنْ هُوَ الْيَوْمَ عَلَى ظَهْرِ الأَرْضِ يُرِيدُ بِذَلِكَ أَنَّهَا تَخْرِمُ ذَلِكَ الْقَرْنَ
