(561) So by your Lord, surely, We shall gather them together, and (also) the Shayatin (devils) (with them), then We shall bring them round Hell on their knees.

(562) Then We shall save those who used to fear Allah and were dutiful to Him. And We shall leave the Zalimun (polytheists and wrongdoers) therein (humbled) to their knees (in Hell).

(563) Nay, but they (the so-called gods) will deny their worship of them, and become opponents to them (on the Day of Resurrection).

(564) So make no haste against them; We only count out to them a (limited) number (of the days of the life of this world and delay their term so that they may increase in evil and sins).

(569) On that Day mankind will follow strictly (the voice of) Allah's caller, no crookedness (that is without going to the right or left of that voice) will they show him (Allah's caller). And all voices will be humbled for the Most Gracious (Allah), and nothing shall you hear but the low voice of their footsteps.

(570) Then they both ate of the tree, and so their private parts became manifest to them, and they began to cover themselves with the leaves of the Paradise for their covering. Thus did Adam disobey his Lord, so he went astray.
