(And if they) the Quraysh (deny thee) O Muhammad: (those before them also denied) those before your own folk, the Quraysh, have also denied their messengers. (Their messengers came unto them with clear proofs (of Allah's Sovereignty)) they came to them with commands, prohibitions and signs, (and with the Psalms and the Scripture) and with the events of the Scriptures of the people of old (giving light) expositing the lawful and the unlawful.
