in Edition Clear Qur'an by Talal Itani / Al-Maaida (The Table)

5:18The Jews and the Christians say, “We are the children of God, and His beloved.” Say, “Why then does He punish you for your sins?” In fact, you are humans from among those He created. He forgives whom He wills, and He punishes whom He wills. To God belongs the dominion of the heavens and the earth and what lies between them, and to Him is the return.

5:43But why do they come to you for judgment, when they have the Torah, in which is God’s Law? Yet they turn away after that. These are not believers.

5:63Why do the rabbis and the priests not prevent them from speaking sinfully and from consuming forbidden wealth? Evil is what they have been doing.

5:84“And why should we not believe in God, and in the truth that has come to us, and hope that our Lord will include us among the righteous people?”
