﴿ 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!”
