Surah Ali 'Imran — Ayah 178 (3:178)
وَلَا يَحۡسَبَنَّ ٱلَّذِينَ كَفَرُوٓاْ أَنَّمَا نُمۡلِي لَهُمۡ خَيۡرٞ لِّأَنفُسِهِمۡۚ إِنَّمَا نُمۡلِي لَهُمۡ لِيَزۡدَادُوٓاْ إِثۡمٗاۖ وَلَهُمۡ عَذَابٞ مُّهِينٞ ١٧٨
English translation (Saheeh International)
And let not those who disbelieve ever think that [because] We extend their time [of enjoyment] it is better for them. We only extend it for them so that they may increase in sin, and for them is a humiliating punishment.
Brief commentary
Those who disbelieve in their Lord and stubbornly resist His sacred law should not think that it is good for them because they are given time and live long, remaining as they are, in disbelief. It is not as they think. They are only given more time to multiply in sin, disobedience upon their disobedience: they will have a humiliating punishment.
