in Edition Clear Qur'an by Talal Itani / Al-Hajj (The Pilgrimage)

22:17Those who believe, and those who are Jewish, and the Sabeans, and the Christians, and the Zoroastrians, and the Polytheists—God will judge between them on the Day of Resurrection. God is witness to all things.

22:28That they may witness the benefits for themselves, and celebrate the name of God during the appointed days, for providing them with the animal livestock. So eat from it, and feed the unfortunate poor.

22:78And strive for God, with the striving due to Him. He has chosen you, and has not burdened you in religion—the faith of your father Abraham. It is he who named you Muslims before, and in this. So that the Messenger may be a witness over you, and you may be witnesses over the people. So pray regularly, and give regular charity, and cleave to God. He is your Protector. What an excellent Protector, and what an excellent Helper.
