A description of how a time ends
Aisha reported it about the passing of the last believers.
إِنَّهُ سَيَكُونُ مِنْ ذَلِكَ مَا شَاءَ اللَّهُ ثُمَّ يَبْعَثُ اللَّهُ رِيحًا طَيِّبَةً فَتَوَفَّى كُلَّ مَنْ فِي قَلْبِهِ مِثْقَالُ حَبَّةِ خَرْدَلٍ مِنْ إِيمَانٍ فَيَبْقَى مَنْ لاَ خَيْرَ فِيهِ فَيَرْجِعُونَ إِلَى دِينِ آبَائِهِمْ
Night and day will not end until people worship what they worshipped before. Then Allah will send a pleasant wind that will take the soul of everyone who has faith the weight of a mustard seed.
The full narration
A'isha reported:I heard Allah's Messenger (ﷺ) as saying: The (system) of night and day would not end until the people have taken to the worship of Lat and 'Uzza. I said: Allah's Messenger, I think when Allah has revealed this verse:" He it is Who has sent His Messenger with right guidance, and true religion, so that He may cause it to prevail upon all religions, though the polytheists are averse (to it)" (ix. 33), it implies that (this promise) is going to be fulfilled. Thereupon he (Allah's Apostle) said: It would happen as Allah would like. Then Allah would send the sweet fragrant air by which everyone who has even a mustard grain of faith in Him would die and those only would survive who would have no goodness in them. And they would revert to the religion of their forefathers
