"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
