(26:191) And indeed, your Lord - He is the Exalted in Might, the Merciful. (26:192) And indeed, the Qur`an is the revelation of the Lord of the worlds. (26:193) The Trustworthy Spirit has brought it down (26:194) Upon your heart, [O Muhammad] - that you may be of the warners - (26:195) In a clear Arabic language.
