There would be none amongst the created beings living on the earth (who would survive this century).  

لَمَا رَجَعَ النَّبِيُّ ﷺ مِنْ تَبُوكَ سَأَلُوهُ عَنِ السَّاعَةِ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَأْتِي مِائَةُ سَنَةٍ وَعَلَى الأَرْضِ نَفْسٌ مَنْفُوسَةٌ الْيَوْمَ  

"There is no soul born upon the earth – meaning today – upon whom will come one hundred years." (Sahih)  

قَالَ رَسُولُ اللَّهِ ﷺ مَا عَلَى الأَرْضِ نَفْسٌ مَنْفُوسَةٌ يَعْنِي الْيَوْمَ تَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ وَأَبِي سَعِيدٍ وَبُرَيْدَةَ  

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)   

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ تَسْأَلُونِي عَنِ السَّاعَةِ وَإِنَّمَا عِلْمُهَا عِنْدَ اللهِ وَأُقْسِمُ بِاللهِ مَا عَلَى الْأَرْضِ مِنْ نَفْسٍ مَنْفُوسَةٍ الْيَوْمَ يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ  

[Machine] The Messenger of Allah ﷺ was asked about the Hour before he died on a month, so he said, "You ask me about the Hour while its knowledge is only with Allah. By the One in whose hand is my soul, I do not know today any person whose life span is a hundred years."  

أَنَّ رَسُولَ اللهِ ﷺ سُئِلَ عَنِ السَّاعَةِ قَبْلَ أَنْ يَمُوتَ بِشَهْرٍ فَقَالَ تَسْأَلُونِي عَنِ السَّاعَةِ وَإِنَّمَا عِلْمُهَا عِنْدَ اللهِ فَوَالَّذِي نَفْسِي بِيَدِهِ مَا أَعْلَمُ الْيَوْمَ نَفْسًا مَنْفُوسَةً يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ  

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  

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)  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ قَبْلَ أَنْ يَمُوتَ بِشَهْرٍ تَسْأَلُونِي عَنِ السَّاعَةِ وَإِنَّمَا عِلْمُهَا عِنْدَ اللهِ وَأُقْسِمُ بِاللهِ مَا عَلَى ظَهْرِ الْأَرْضِ مِنْ نَفْسٍ مَنْفُوسَةٍ الْيَوْمَ يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ  

[Machine] On the authority of the Prophet ﷺ who said: "You ask me about the Hour (i.e., Day of Judgment), while my soul is in the Hand of Allah, there is no soul on Earth that is more knowledgeable about when the Hour will happen than a hundred years."  

عَنِ النَّبِيِّ ﷺ قَالَ «تَسْأَلُونِي عَنِ السَّاعَةِ وَالَّذِي نَفْسِي بِيَدِهِ مَا عَلَى الْأَرْضِ نَفْسٌ مَنْفُوسَةٌ يَأْتِي عَلَيْهَا مِائَةُ سَنَةٍ»  

"لا تَأتِي مِائَةُ سَنَةٍ وَعَلَى الأَرْضِ نَفْسٌ مَنْفُوسَةٌ الْيَوْمَ".  

"مَا عَلى الأرْض نَفْسٌ مَنْفُوسة يَأتِي عَلَيها مِائَةُ سَنَةٍ".  

"يَسْأَلُونِى عَن السَّاعَةِ! ! والَّذِى نَفْسِى بِيَدِهِ مَا عَلى الأَرْضِ نَفْسٌ مَنْفُوسَةٌ اليَوْمَ يَأتِى عَلَيْهَا مِائَةُ سَنَةٍ".
