Surah Al-Kahf 18:58

وَرَبُّكَ ٱلْغَفُورُ ذُو ٱلرَّحْمَةِ ۖ لَوْ يُؤَاخِذُهُم بِمَا كَسَبُوا۟ لَعَجَّلَ لَهُمُ ٱلْعَذَابَ ۚ بَل لَّهُم مَّوْعِدٌ لَّن يَجِدُوا۟ مِن دُونِهِۦ مَوْئِلًا

And your Lord is the Forgiving, the possessor of mercy. If He were to impose blame upon them for what they earned, He would have hastened for them the punishment. Rather, for them is an appointment from which they will never find an escape.

Translation: Saheeh International

Tafsir

And your Lord is the Forgiver Full of Mercy. Were He to take them to task in this world for what they have earned He would have hastened for them the chastisement therein; but they have a tryst which is the Day of Resurrection from which they will not find any escape any refuge.
