Sura 30 Ar-Rum (The Romans), ayah 36

1. وَإِذَا أَذَقْنَا النَّاسَ رَحْمَةً فَرِحُوا بِهَا ۖ وَإِنْ تُصِبْهُمْ سَيِّئَةٌ بِمَا قَدَّمَتْ أَيْدِيهِمْ إِذَا هُمْ يَقْنَطُونَ

   And when We let the people taste mercy, they rejoice therein, but if evil afflicts them for what their hands have put forth, immediately they despair.

   30:36
