Surah Al-A'raf — Ayah 34 (7:34)
وَلِكُلِّ أُمَّةٍ أَجَلٞۖ فَإِذَا جَآءَ أَجَلُهُمۡ لَا يَسۡتَأۡخِرُونَ سَاعَةٗ وَلَا يَسۡتَقۡدِمُونَ ٣٤
English translation (Saheeh International)
And for every nation is a [specified] term. So when their time has come, they will not remain behind an hour, nor will they precede [it].
Brief commentary
Every generation and people are given a fixed time. If their decreed time arrives, they cannot delay it, even by a small amount, and they cannot advance it.
