Qul la amliku linafsee nafAAan waladarran illa ma shaa Allahuwalaw kuntu aAAlamu alghayba lastakthartu mina alkhayriwama massaniya assoo-o in ana illanatheerun wabasheerun liqawmin yu/minoon

Say, "I hold not for myself [the power of] benefit or harm, except what Allāh has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe."

Say, “I have no power to bring a benefit or a harm to myself, except that which Allah wills. If I had the knowledge of the Unseen, I would have accumulated a lot of good things, and no evil would have ever touched me. I am but a warner, and a herald of good news for a people who believe.”
