﴿ وَإِذَآ أَذَقْنَا ٱلنَّاسَ رَحْمَةًۭ فَرِحُوا۟ بِهَا ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌۢ بِمَا قَدَّمَتْ أَيْدِيهِمْ إِذَا هُمْ يَقْنَطُونَ ﴾

“And [thus it is:] when we let men taste [Our] grace, they rejoice in it; but if evil befalls them as an outcome of what their own hands have wrought lo! they lose all hope!”

And when We let people that is people such as the disbelievers of Mecca and others taste some mercy some grace they exult in it an exultation of arrogance. But if some evil some hardship befalls them for what their own hands have sent ahead behold! they despair of mercy. It is in the nature of a believer to give thanks in times of grace and to hope for mercy from his Lord in times of hardship.
