I heard Messenger of Allah ﷺ as saying this one month before his death: You asked me about the Last Hour whereas its knowledge is with Allah. I, however, take an oath and say that none upon the earth, the created beings (from amongst my Companions), would survive at the end of one hundred years. (Using translation from Muslim 2538a)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ قَبْلَ أَنْ يَمُوتَ بِشَهْرٍ تَسْأَلُونِي عَنِ السَّاعَةِ وَإِنَّمَا عِلْمُهَا عِنْدَ اللهِ أُقْسِمُ بِاللهِ مَا عَلَى الْأَرْضِ نَفْسٌ مَنْفُوسَةٌ الْيَوْمَ يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ
