Quran 7:35 — The Purgatory (Al-A'araf)

O children of Adam, when messengers come to you from among you, and recite My revelations to you, those who take heed and lead a righteous life, will have nothing to fear, nor will they grieve.

[7:34] For each community, there is a predetermined life span. Once their interim comes to an end, they cannot delay it by one hour, nor advance it.

[7:36] As for those who reject our revelations, and are too arrogant to uphold them, they have incurred Hell, wherein they abide forever.
