the Holy Qur'an

If then they turn back, say ye: "Bear witness that we (at least) are Muslims (bowing to God's Will). (3:64)

Soon shall We cast terror into the hearts of the Unbelievers, for that they joined companions with God, for which He had sent no authority: their abode will be the Fire: And evil is the home of the wrong-doers! (3:151)
