Surah No. 16, An Nahl, Ayat No. 61

وَلَوْ يُؤَاخِذُ اللّهُ النَّاسَ بِظُلْمِهِم مَّا تَرَكَ عَلَيْهَا مِن دَآبَّةٍ وَلَكِن يُؤَخِّرُهُمْ إلَى

o أَجَلٍ مُّسَمًّى فَإِذَا جَاء أَجَلُهُمْ لاَ يَسْتَأْخِرُونَ سَاعَةً وَلاَ يَسْتَقْدِمُونَ

If Allah were to punish men for their wrongdoing instantly, He would not leave, a single living creature on the (earth),: but He gives them respite for an appointed Term: when their Term comes they cannot delay (the punishment) for an hour, nor can advance it.
