Surah Al-Fath (The Victory): (13) And whoever does not believe...

Regarding our previous statement concerning: {And you thought an evil thought} (Al-Fath: 12), [this verse implies] another type of assumption different from what was mentioned in {Nay, you thought an evil thought}.

This is because we explained that this assumption was their belief that Allah would break His promise, or their assumption that the Messenger was a liar.

Therefore, [Allah says]: {And whoever does not believe in Allah and His Messenger}—meaning, whoever assumes Allah will break His promise and the Messenger is a liar—{then indeed, We have prepared for him a fierce Fire}.

And the use of {for the disbelievers} instead of saying, "then indeed, We have prepared for him," carries a benefit, which is generalization. It is as if Allah Almighty said: Whoever does not believe in Allah is among the disbelievers, and We have prepared a fierce Fire for the disbelievers.

{And to Allah belongs the dominion of the heavens and the earth. He forgives whom He wills and punishes whom He wills. And Allah is ever, Forgiving and Merciful.}
