Ar-Rum 30:58

Walaqad darabna linnasifee hatha alqur-ani min kulli mathalin wala-inji/tahum bi-ayatin layaqoolanna allatheena kafarooin antum illa mubtiloon

And We have certainly presented to the people in this Qur’ān from every [kind of] example. But, [O Muḥammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers."

Indeed We have given in this Qur’ān all kinds of examples for the benefit of mankind. (Still) if you bring to them a sign, the disbelievers will certainly say, “You are nothing but men of falsehood.”
