Sahih International
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.
Muhsin Khan
When harm touches man, he calls to Us (for help), then when We have (rescued him from that harm and) changed it into a favour from Us, he says: “Only because of knowledge (that I possess) I obtained it.” Nay, it is only a trial, but most of them know not!
Pickthall
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.
Yusuf Ali
Now, when trouble touches man, he cries to Us: But when We bestow a favour upon him as from Ourselves, he says, “This has been given to me because of a certain knowledge (I have)!” Nay, but this is but a trial, but most of them understand not!
Shakir
So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.
Dr. Ghali
So when an adversity touches man, he invokes Us; thereafter when We grant him a favor from Us, he says, “Surely I have been brought it only because of (my) knowledge.” No indeed, it is a temptation, but most of them do not know.
