Hadith 2953
Anas bin Malik (RA) reported that a person asked Allah's Apostle (ﷺ) : When would the Last Hour come? Thereupon Allah's Messenger (ﷺ) kept quiet for a while, then looked at a young boy in his presence belonging to the tribe of Azd Shanilwa and he said: If this boy lives he would not grow very old till the Last Hour would come to you. Anas said that this young boy was of our age during those days.
