A young boy of Mughira b. Shu'ba happened to pass by (the Holy Prophet) and he was of my age. Thereupon Allah's Apostle ﷺ said: If he lives long he would not grow very old till the Last Hour would come (to the old people of this generation).
النَّبِيُّ ﷺ إِنْ يُؤَخَّرْ هَذَا فَلَنْ يُدْرِكَهُ الْهَرَمُ حَتَّى تَقُومَ السَّاعَةُ
