He was one of the chief associates of Mu’awiyah radi Allahu anhu.
He passed away in the year 56 AH.
Radi Allahu anhu wa ardah.
The coming of the promised Dajjal is a true reality.

Hadith Commentary:
It is Allah Almighty’s principle that He tests His believing servants by subjecting them to various trials. Among these trials is the tribulation (fitnah) of the Dajjal. Allah Almighty will grant him great power. He will send cool breezes for his followers. He will cause rains to fall. He will make crops and grain grow from the earth. In short, he will provide means of prosperity for them, and those who call him a liar, he will afflict them with famine and poverty. He will throw them into the fire that he holds in one of his hands, which in reality will be Paradise. But all of this will occur by the permission of Allah Almighty, and if Allah Almighty does not permit, he will not be able to do anything. In one hadith, it is mentioned that what people will perceive as fire will in fact be cool water. (: Sahih al-Bukhari, Ahadith al-Anbiya, Hadith: 3450)

Benefits and Issues:
The phrase (هُوَ أَهْوَنُ عَلَى اللَّهِ مِنْ ذَلِكَ)
has one meaning which has been adopted in the translation, that is, the Dajjal is so contemptible that Allah will not grant him these things; rather, it will merely be an apparent deception.
Its second possible meaning is that, when despite being so contemptible in the sight of Allah, he has been given the ability to display such great feats, then food and water are trivial matters.
Hafiz Ibn Hajar al-Asqalani rahimahullah has also mentioned another meaning: that the Dajjal is so contemptible that Allah, exalted is He, will not allow these feats to become proof of his truthfulness; rather, He will manifest such things by which his falsehood will become clear, for example:
The clear sign of his disbelief (the word “K, F, R” written on his forehead),
which every literate and illiterate person will be able to read. (Fath al-Bari: 13/116)

Benefit:
At the end of this hadith in Sahih al-Bukhari (7122), there is an addition: I said, "People say: There will be a mountain of bread and a river of water with him." The Prophet sallallahu alayhi wa sallam said:
"It is even easier than that for Allah."
Among the major signs of the Day of Judgment is the trial of the Dajjal. The word "Dajjal" is derived from "dajal," which means: to deceive, to conceal the truth, and to display trickery. Near the end of times, the Dajjal will appear and display various tricks, to the extent that he will claim to be a deity, but he himself will be one-eyed. On his forehead will be written: K F R (disbeliever). Declaring the Dajjal to be the greatest trial, the Noble Prophet sallallahu alayhi wa sallam said:
"O people! Since Allah created the children of Adam, there has never been a trial on earth greater than the trial of the Dajjal, and Allah has not sent any prophet except that he warned his nation about him." [سنن ابن ماجه: 4077]
