in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:29Fight those who do not believe in God, nor in the Last Day, nor forbid what God and His Messenger have forbidden, nor abide by the religion of truth—from among those who received the Scripture—until they pay the due tax, willingly or unwillingly.

9:53Say, “Whether you spend willingly or unwillingly, it will not be accepted from you. You are evil people.”
