Once he waited for Al-Hasan and he did not show up till it was about the usual time for him to start his speech; then he came and apologized saying, "Our neighbors invited us." Then he added, "Narrated Anas, 'Once we waited for the Prophet ﷺ till it was midnight or about midnight. He came and led the prayer, and after finishing it, he addressed us and said, 'All the people prayed and then slept and you had been in prayer as long as you were waiting for it." Al-Hasan said, "The people are regarded as performing good deeds as long as they are waiting for doing good deeds." Al-Hasan's statement is a portion of Anas's [??] Hadith from the Prophet ﷺ .  

انْتَظَرْنَا الْحَسَنَ وَرَاثَ عَلَيْنَا حَتَّى قَرُبْنَا مِنْ وَقْتِ قِيَامِهِ فَجَاءَ فَقَالَ دَعَانَا جِيرَانُنَا هَؤُلاَءِ ثُمَّ قَالَ قَالَ أَنَسٌ نَظَرْنَا النَّبِيَّ ﷺ ذَاتَ لَيْلَةٍ حَتَّى كَانَ شَطْرُ اللَّيْلِ يَبْلُغُهُ فَجَاءَ فَصَلَّى لَنَا ثُمَّ خَطَبَنَا فَقَالَ أَلاَ إِنَّ النَّاسَ قَدْ صَلَّوْا ثُمَّ رَقَدُوا وَإِنَّكُمْ لَمْ تَزَالُوا فِي صَلاَةٍ مَا انْتَظَرْتُمُ الصَّلاَةَ قَالَ الْحَسَنُ وَإِنَّ الْقَوْمَ لاَ يَزَالُونَ بِخَيْرٍ مَا انْتَظَرُوا الْخَيْرَ قَالَ قُرَّةُ هُوَ مِنْ حَدِيثِ أَنَسٍ عَنِ النَّبِيِّ ﷺ  

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
