Saba · 34:3

3. Those who disbelieved in Allah said, “The hour will never come to us!” O Messenger! Say to them: “No, by Allah, the very hour that you reject will definitely come to you, but its time is only known to Allah. He (may He be glorified) is the knower of whatever is hidden such as the hour, even the equivalent of the smallest ant is not hidden from His knowledge, nor anything smaller than that in the heavens or on Earth or larger, except that it is recorded in a clear book, which is the Preserved Tablet in which everything that is to happen until the Day of Judgement is recorded.”
