Rasul Allah said about Imam Mahdi (as) Allah will rectify Him in a single night, the correct understanding of what that means is that Allah will raise Him in a single night.
What that itself means in detail is that Allah will open something for him to do and that task in a single night will raise him above the Mala’ikah so they will follow him, essentially so they follow Him like they prostrated to Sayidinah Adam (as).
This is what Rasul Allah (saws) taught me, recently Allah opened a task for me to perform and after accomplishing it Rasul Allah (saws) said in front of the Jinn and Mala’aikah that I saw watching “Allah has raised Rami” (in a single night), the intent behind phrasing was a lesson meant to teach me that in essence this is what Allah will do for Imam mahdi (as), on another level, he will raise Him above all the Mala’ikah.
Not long after this I surpassed the Dajjaal and was able to describe Him as i did in the chapters dedicated to him in my book on syria and the hour, regarding which Rasul Allah (saws) said to me, “people will not find another person who will be able to complete these words against him”.
The heart needs to encompass a thing, be more than it, to see it clearly, in order to know how to describe it, and the subject of the dajjal is shrouded in kufr and sihr, the spiritual sight of your heart needs to penetrate through that darkness around him in order to see him, and you need to be more than his kufr in order to surpass him.
Insha Allah understand the task Allah set before us and the reason for me covering these subjects, the descriptions I have given are the best descriptions people will find regarding him until his death, and what I wrote is the straightest line to him you will ever find (Qala Rasul Allah).
