Al-Mulk 67:29

Qul huwa arrahmanu amannabihi waAAalayhi tawakkalna fasataAAlamoona man huwa fee dalalinmubeen

Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error."

Say, “He is the RaHmān; we have believed in Him, and in Him we placed our trust. So, you will soon come to know who is in open error.”
