(6:15) Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." (6:16) He from whom it is averted that Day - [Allah] has granted him mercy. And that is the clear attainment. (6:17) And if Allah should touch you with adversity, there is no remover of it except Him. And if He touches you with good - then He is over all things competent. (6:18) And He is the subjugator over His servants. And He is the Wise, the Acquainted [with all]. (6:19) Say, "What thing is greatest in testimony?" Say, "Allah is witness between me and you. And this Qur`an was revealed to me that I may warn you thereby and whomever it reaches. Do you [truly] testify that with Allah there are other deities?" Say, "I will not testify [with you]." Say, "Indeed, He is but one God, and indeed, I am free of what you associate [with Him]." (6:20) Those to whom We have given the Scripture recognize it as they recognize their [own] sons. Those who will lose themselves [in the Hereafter] do not believe. (6:21) And who is more unjust than one who invents about Allah a lie or denies His verses? Indeed, the wrongdoers will not succeed.
