Why did Allah Almighty specifically choose torment by fire in the the Hereafter?

A Muslim must submit to the actions of Allah and His Law. Allah is not questioned about what He does, due to the perfection of His wisdom, mercy, and knowledge, whereas His servants will be questioned. Allah has informed us about the torment of the Hereafter so that we may beware of it, not to question its wisdom. The torment of the Hereafter is not confined to Hellfire alone; rather, it includes types of physical and spiritual torment, such as being deprived of seeing Allah, looking at Him, and His speech, and the companionship of evil people, in addition to Al-Zamhareer (intense cold), chains and shackles, and the trees of Zaqqum and Hameem.
