Mishkat al-Masabih 27 Fitan كتاب الفتن 131

وَعَن جَابر قا ل: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ قَبْلَ أَنْ يَمُوتَ بِشَهْرٍ: «تَسْأَلُونِي عَنِ السَّاعَةِ؟ وَإِنَّمَا عِلْمُهَا عِنْدَ اللَّهِ وَأُقْسِمُ بِاللَّهِ مَا عَلَى الْأَرْضِ مِنْ نَفْسٍ مَنْفُوسَةٍ يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ وَهِيَ حَيَّةٌ يَوْمَئِذٍ» . رَوَاهُ مُسْلِمٌ

Jabir told that he heard the Prophet say a month before he died, “You ask me about the last hour, but God alone has knowledge of it. I swear by God that no one already born who lives a hundred years will be alive that day.” Muslim transmitted it.
