Allah has promised that He will uncover the veil from their hearts; He said: “No indeed! The record of the pious is indeed in ‘Illiyun. And what will show you what is ‘Illiyun? It is a written record, witnessed by those brought near [to Allah].” ‘Illiyun is the celestial heavenly world.
He, the Almighty said: “Thus did we show Ibrahim the dominion of the heavens and the earth, that he might be of those who possess certitude.” Quran 6: 75 This ultimate goal is the same as that also mentioned in another verse: “Thus we established Joseph in the land and that We might teach him the interpretation of dreams.” Quran 12:21 And, “And that God may know those who have sincerely believed, and that He may take witness from among you.” But this goal is not similar to that of this verse: “So that mankind may not have any argument against Allah, after the [sending of the] apostles.” The verse establishes that Allah, the Almighty will show His worshippers who have certitude the dominion of the heavens and the earth.
