﴿ وَلَئِنْ أَذَقْنَا ٱلْإِنسَٰنَ مِنَّا رَحْمَةًۭ ثُمَّ نَزَعْنَٰهَا مِنْهُ إِنَّهُۥ لَيَـُٔوسٌۭ كَفُورٌۭ ﴾

“And thus it is: if We let man taste some of Our grace, and then take it away from him -behold, he abandons all hope, forgetting all gratitude [for Our past favours].”

(And if We cause man) the disbeliever (to taste some mercy) a blessing (from Us and afterward withdraw it from him, lo! he is despairing) he becomes the most despairing and despondent thing from Allah's mercy, (thankless) he denies Allah's blessing and is not grateful.
