'Abdullah b. Umar reported that Allah's Messenger (ﷺ) 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 (ﷺ) which had been uttered pertaining to one hundred years. Allah's Messenger (ﷺ) 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.
This hadith has been transmitted by Zuhri on the authority of Ma'mar.
Jabir b. 'Abdullah reported
I heard Allah's Messenger (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.
This hadith has been narrated on the authority of Ibn Juraij with the same chain of transmitters, but there is no mention of the words
" one month before his death".
Jabir b. 'Abdullah reported Allah's Apostle (ﷺ) as saying one mouth before his death (or something like it)
None amongst the created beings who had been living by that time (during the lifetime of Allah's Apostle).... 'Abd al-Rahman has interpreted these words of Allah's Apostle (ﷺ) as: The ages (of the people) would be diminished.
This hadith has been reported on the authority of Sulaiman Taimi through other chains of transmitters.
Abu Sa'id reported that when Allah's Apostle (ﷺ) came back from Tabuk they (his Companions) asked about the Last Hour. Thereupon Allah's Messenger (ﷺ) said
There would be none amongst the created beings living on the earth (who would survive this century).
Jabir b. 'Abdullah reported that Allah's Messenger (ﷺ) said
None amongst the created beings (from my Companions) would survive after one hundred years. Salim said: We made a mention of it to him (Jabir), whereupon he said: It means those who had been living on that day.
