﴿ 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”

When a man flouts the Truth, but does not immediately receive the punishment for this, it makes him arrogant. The fact of his going scot free is only due to the latitude given to him during the period of trial, and not because of any real freedom. If the individual is keen to learn a lesson, he must consider the fate of his predecessors, from which he may learn how to conduct his present life. On the face of this earth, different nations and different cultures have risen from time to time and have subsequently been destroyed. When earlier generations were punished for their disobedience, why should later generations not meet the same fate?
