Verse 49

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

Then when an adversity touches the human being, he calls upon Us, but when We relieve it from him as a blessing from Us; he says I achieved this by my own knowledge. However, it is a test, but most of them do not realize it.
