‘Abdullah b. Umar reported that Allah’s Messenger (may peace be upon him) led us ‘Isha prayer at the latter part of the night and when he had concluded it by salutations he stood up and said: Have you seen this night of yours? At the end of one hundred years after this none would survive on the surface of the earth (from amount my Companions). Ibn Umar said: People were (not understanding) these words of the Messenger of Allah (may peace be upon him) which had been uttered pertaining to one hundred years. Allah’s Messenger (may peace be upon him) in fact meant (by these words) that on that day none from amongst those who had been living upon the earth (from amongst his Companions) would survive (after one hundred years) and that would be the end of this generation.
Chapter : Meaning of the saying of the Prophet (may peace be upon him): “No person would survive after a century who is living by this time of mine”.
