وَرَبُّكَ ٱلْغَفُورُ ذُو ٱلرَّحْمَةِ ۖ لَوْ يُؤَاخِذُهُم بِمَا كَسَبُوا۟ لَعَجَّلَ لَهُمُ ٱلْعَذَابَ ۚ بَل لَّهُم مَّوْعِدٌۭ لَّن يَجِدُوا۟ مِن دُونِهِۦ مَوْئِلًۭا
Thy Lord is the Forgiver, Full of Mercy. If He took them to task (now) for what they earn, He would hasten on the doom for them; but theirs is an appointed term from which they will find no escape.
