6:19Say, “What thing is more solemn in testimony?” Say, “God is Witness between you and me. This Quran was revealed to me, that I may warn you with it, and whomever it may reach. Do you indeed testify that there are other gods with God?” Say, “I myself do not testify.” Say, “He is but One God, and I am innocent of your idolatry.”

6:62Then they are brought back to God, their True Master. Unquestionably, His is the judgment, and He is the Swiftest of reckoners.

6:130“O assembly of jinn and humans, did there not come to you messengers from among you, relating to you My revelations, and warning you of the meeting of this Day of yours?” They will say, “We testify against ourselves.” The life of the world seduced them. They will testify against themselves that they were disbelievers.

6:150Say, “Produce your witnesses who would testify that God has prohibited this.” If they testify, do not testify with them. And do not follow the whims of those who deny Our revelation, and those who do not believe in the Hereafter, and those who equate others with their Lord.

6:165It is He who made you successors on the earth, and raised some of you in ranks over others, in order to test you through what He has given you. Your Lord is Quick in retribution, and He is Forgiving and Merciful.
