﴿ وَإِن يُكَذِّبُوكَ فَقَدْ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ جَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ وَبِٱلزُّبُرِ وَبِٱلْكِتَٰبِ ٱلْمُنِيرِ ﴾

“And if they give thee the lie - even so gave the lie to the truth [many of] those who lived before their time, [when] there came unto them their apostles with all evidence of the truth, and with books of divine wisdom, and with light-giving revelation;”

(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.
