Attitude of man when Allah lets him taste good after evil

اعوذ بالله من الشيطن الرجيم

Surah 11. Hud, Verse 10:

وَلَئِنْ أَذَقْنَاهُ نَعْمَاءَ بَعْدَ ضَرَّاءَ مَسَّتْهُ لَيَقُولَنَّ ذَهَبَ السَّيِّئَاتُ عَنِّي إِنَّهُ لَفَرِحٌ فَخُورٌ

Translation:

But if We let him taste good (favour) after evil (poverty and harm) has touched him, he is sure to say: "Ills have departed from me." Surely, he is exultant, and boastful (ungrateful to Allah).
