The meaning of the word ‘Qaht’ is scourge, poverty and scarcity. Qahtani is one of those individuals that will appear before the Mahdi and shed blood.
God makes negative and positive powers intellectually fight one another and makes Islam prevail in the end. Negative powers will ultimately be defeated. And the movement of the Mahdi, which is a positive power, will ultimately be dominant.
Mahdi, antichrist, sufyan, kahtani are all figures of End Times and they can’t be recognized before hadiths about them come true.
