It was narrated from 'Abdullah bin 'Umar, that he said:
The Messenger of Allah(s.a.w) led us in Salat one night for Salat Al-'Isha' during the end of his life. When he said the Taslim he stood and said: 'Do you see this night of yours, upon the head of one hundred years from it there shall not remain anyone who is upon the surface of the earth today.' Ibn 'Umar said: 'So, people misunderstood the saying of the Messenger of Allah(s.a.w), in what they say based on these Ahadith about one hundred years. The Messenger of Allah(s.a.w) only said: 'There shall not remain anyone who is upon the surface today.' Meaning, that generation would end.
