Surah 31. Luqman, Ayah 9

Commenting on the above three verses, Razi points out, firstly, that the deliberate contrast between the plural in the promise of "gardens (jannat) of bliss" and the singular in that of "suffering" ('adhab) is meant to show that God's grace surpasses His wrath (cf. note [10] on 6:12 ), and, secondly, that the use of the expression "to abide therein" in connection with the mention of paradise only, and not with that of otherworldly suffering (or hell), is an indication that whereas the enjoyment of the former will be unlimited in duration, suffering in what is described as "hell" will be limited.

He is Exalted in power, and can carry out His Will, and nothing can stop the carrying out of His promise. He is also infinitely Wise: His promise is therefore full of meaning: it is not merely without purpose: it has a place in the Universal Plan.
