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

6:15Say, “I fear, should I defy my Lord, the punishment of a tremendous Day.”

6:68When you encounter those who gossip about Our revelations, turn away from them, until they engage in another topic. But should Satan make you forget, do not sit after the recollection with the wicked people.

6:81And why should I fear those you associate with Him, and you do not fear associating others with God for which He sent down to you no authority? Which side is more entitled to security, if you are aware?”

6:91They do not value God as He should be valued, when they say, “God did not reveal anything to any human being.” Say, “Who revealed the Scripture which Moses brought—a light and guidance for humanity?” You put it on scrolls, displaying them, yet concealing much. And you were taught what you did not know—neither you, nor your ancestors. Say, “God;” then leave them toying away in their speculation.

6:119And why should you not eat of that over which the Name of God is pronounced, when He has detailed for you what is prohibited for you, unless you are compelled by necessity? Many lead astray with their opinions, through lack of knowledge. Your Lord knows best the transgressors.
