Ali 'Imran 3:184

Fa-in kaththabooka faqad kuththibarusulun min qablika jaoo bilbayyinati wazzuburiwalkitabi almuneer

Then if they deny you, [O Muḥammad] - so were messengers denied before you, who brought clear proofs and written ordinances and the enlightening Scripture.

Then if they reject you, then messengers have been rejected before you. They came with clear signs and the Scriptures and the enlightening Book.
