in Edition Clear Qur'an by Talal Itani / Al-An'aam (The Cattle)

6:35If you find their rejection hard to bear, then if you can, seek a tunnel into the earth, or a stairway into the heaven, and bring them a sign. Had God willed, He could have gathered them to guidance. So do not be of the ignorant.

6:52And do not drive away those who call upon their Lord, morning and evening, seeking His attention. You are not accountable for them in any way, nor are they accountable for you in any way. If you drive them away, you would be one of the unjust.

6:57Say, “I stand on clear evidence from my Lord, and you have rejected Him. I do not possess what you seek me to hasten; the decision belongs solely to God. He states the truth, and He is the Best of Judges.”

6:58Say, “If I possessed what you seek me to hasten, the matter between you and me would have been settled. God is well aware of the unjust.”

6:114“Shall I seek a judge other than God, when He is the One who revealed to you the Book, explained in detail?” Those to whom We gave the Book know that it is the truth revealed from your Lord. So do not be of those who doubt.

6:164Say, “Am I to seek a Lord other than God, when He is the Lord of all things?” No soul gets except what it is due, and no soul bears the burdens of another. Then to your Lord is your return, then He will inform you regarding your disputes.
