6:56Say, “I am forbidden from worshiping those you pray to besides God.” Say, “I will not follow your desires; else I would be lost and not be of those guided.”

6:70So leave alone those who take their religion for play and pastime, and whom the worldly life has deceived. But remind with it, lest a soul becomes damned on account of what it has earned. It has no helper or intercessor besides God. Even if it offers every equivalent, none will be accepted from it. These are the ones who are delivered to perdition by their actions. They will have a drink of scalding water, and a painful punishment, because they used to disbelieve.

6:71Say, “Shall we invoke besides God something that can neither benefit us nor harm us, and turn back on our heels after God has guided us; like someone seduced by the devils and confused on earth, who has friends calling him to guidance: 'Come to us'?” Say, “The guidance of God is the guidance, and we are commanded to surrender to the Lord of the Universe.”

6:108Do not insult those they call upon besides God, lest they insult God out of hostility and ignorance. We made attractive to every community their deeds. Then to their Lord is their return, and He will inform them of what they used to do.
