Quran 7:34 — The Purgatory (Al-A'araf)

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.

[7:33] Say, "My Lord prohibits only evil deeds, be they obvious or hidden, and sins, and unjustifiable aggression, and to set up beside GOD powerless idols, and to say about GOD what you do not know."

[7:35] 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.
