infidelity
in Edition Clear Qur'an by Talal Itani / Aal-i-Imraan (The Family of Imraan)

3:80Nor would he command you to take the angels and the prophets as lords. Would he command you to infidelity after you have submitted?

3:167And that He may know the hypocrites. And it was said to them, “Come, fight in the cause of God, or contribute.” They said, “If we knew how to fight, we would have followed you.” On that day they were closer to infidelity than they were to faith. They say with their mouths what is not in their hearts; but God knows what they hide.
