Surah Ar-Rum — Ayah 36 (30:36)
وَإِذَآ أَذَقۡنَا ٱلنَّاسَ رَحۡمَةٗ فَرِحُواْ بِهَاۖ وَإِن تُصِبۡهُمۡ سَيِّئَةُۢ بِمَا قَدَّمَتۡ أَيۡدِيهِمۡ إِذَا هُمۡ يَقۡنَطُونَ ٣٦
English translation (Saheeh International)
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.
Brief commentary
And when I give the people a taste of some of My bounties, i.e. health and wealth, they become happy with it; a happiness based on arrogance and pride. And if something that harms them reaches them, i.e. illness or poverty due to the sins they commit, they begin losing hope in the mercy of Allah and in the difficulty going away from them.
