Az-Zumar 39:49

Fa-itha massa al-insana durrundaAAana thumma itha khawwalnahuniAAmatan minna qala innama ooteetuhu AAalaAAilmin bal hiya fitnatun walakinna aktharahum layaAAlamoon

And when adversity touches man, he calls upon Us; then when We bestow on him a favor from Us, he says, "I have only been given it because of [my] knowledge." Rather, it is a trial, but most of them do not know.

When man is visited by a trouble, he prays to Us, but when, after that, We favor him with some blessing from Us, he says, “This is given to me because of (my) knowledge.” No, but this is a trial, yet most of them do not know.
