Allah's Mercy Balanced with Justice

وَلَوْ يُؤَاخِذُ ٱللَّهُ ٱلنَّاسَ بِظُلْمِهِم مَّا تَرَكَ عَلَيْهَا مِن دَآبَّةٍ وَلَـٰكِن يُؤَخِّرُهُمْ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۖ فَإِذَا جَآءَ أَجَلُهُمْ لَا يَسْتَـْٔخِرُونَ سَاعَةً ۖ وَلَا يَسْتَقْدِمُونَ

And if Allāh were to impose blame on the people for their wrongdoing, He would not have left upon it [i.e., the earth] any creature, but He defers them for a specified term. And when their term has come, they will not remain behind an hour, nor will they precede [it].
