Our Lord! surely Thou art the Gatherer of men on a day about which there is no doubt; surely Allah will not fail (His) promise.

Our Lord! and grant us what Thou hast promised us by Thy messengers; and disgrace us not on the day of resurrection; surely Thou dost not fail to perform the promise.

And We appointed with Musa a time of thirty nights and completed them with ten (more), so the appointed time of his Lord was complete forty nights, and Musa said to his brother Haroun: Take my place among my people, and act well and do not follow the way of the mischief-makers.

So Musa returned to his people wrathful, sorrowing. Said he: O my people! did not your Lord promise you a goodly promise: did then the time seem long to you, or did you wish that displeasure from your Lord should be due to you, so that you broke (your) promise to me?

And they ask you to hasten on the punishment, and Allah will by no means fail in His promise, and surely a day with your Lord is as a thousand years of what you number.

But (as for) those who are careful of (their duty to) their Lord, they shall have high places, above them higher places, built (for them), beneath which flow rivers; (this is) the promise of Allah: Allah will not fail in (His) promise.
