Quran 39:49 Az-Zumar, ayah 49 of 75

فَإِذَا مَسَّ ٱلْإِنسَـٰنَ ضُرٌّ دَعَانَا ثُمَّ إِذَا خَوَّلْنَـٰهُ نِعْمَةً مِّنَّا قَالَ إِنَّمَآ أُوتِيتُهُۥ عَلَىٰ عِلْمٍۭ ۚ بَلْ هِىَ فِتْنَةٌ وَلَـٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ ۝٤٩

39:49 Now when hurt toucheth a man he crieth unto Us, and afterward when We have granted him a boon from Us, he saith: Only by force of knowledge I obtained it. Nay, but it is a test. But most of them know not.
