﴿ وَلَئِنْ أَذَقْنَٰهُ نَعْمَآءَ بَعْدَ ضَرَّآءَ مَسَّتْهُ لَيَقُولَنَّ ذَهَبَ ٱلسَّيِّـَٔاتُ عَنِّىٓ ۚ إِنَّهُۥ لَفَرِحٌۭ فَخُورٌ ﴾

“And thus it is: if We let him taste ease and plenty after hardship has visited him, he is sure to say, "Gone is all affliction from me!"-for, behold, he is given to vain exultation, and glories only in himself.”

(And if We cause him) i.e. the disbeliever (to taste grace after some misfortune) after some hardship (that had befallen him, he saith) i.e. the disbeliever: (The ills) hardships (have gone from me. Lo! he is exultant) arrogant, (boastful) about Allah's blessings and does not give thanks;
