﴿ وَرَبُّكَ ٱلْغَفُورُ ذُو ٱلرَّحْمَةِ ۖ لَوْ يُؤَاخِذُهُم بِمَا كَسَبُوا۟ لَعَجَّلَ لَهُمُ ٱلْعَذَابَ ۚ بَل لَّهُم مَّوْعِدٌۭ لَّن يَجِدُوا۟ مِن دُونِهِۦ مَوْئِلًۭا ﴾

“Yet, [withal,] thy Sustainer is the Truly-Forgiving One, limitless in His grace. Were He to take them [at once] to task for whatever [wrong] they commit, He would indeed bring about their speedy punishment [then and there]: but nay, they have a time-limit beyond which they shall find no redemption”

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.
