Abomination of Holding Conversation after 'Isha' (Night) Prayer
وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ صَلَّى الْعِشَاءِ فِي آخِرِ حَيَاتِهِ، فَلَمَّا سَلَّمَ، قَالَ: أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ؟ فَإِنَّ عَلَى رَأْسِ مِائَةِ سَنَةٍ لاَ يبقي مِمَّنْ هُوَ عَلَى ظَهْرِ الأَرْضِ اليوم أحد ((مُتَّفَقٌ عَلَيْهِ)).
Ibn 'Umar (May Allah be pleased with them) said: Once, towards the end of his life, the Messenger of Allah (ﷺ) concluded the 'Isha' (night) prayer and said, "After one hundred years from tonight none of the people on the surface of the earth will survive." [Al- Bukhari and Muslim].
