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." (Using translation from Bukhārī 116)  

صَلَّى بِنَا رَسُولُ اللهِ ﷺ ذَاتَ لَيْلَةٍ صَلَاةَ الْعِشَاءِ فِي آخِرِ حَيَاتِهِ فَلَمَّا سَلَّمَ قَالَ «أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ فَإِنَّ عَلَى رَأْسِ مِائَةِ سَنَةٍ مِنْهَا لَا يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الْأَرْضِ أَحَدٌ»
