Al-An'am 6:147

Fa-in kaththabooka faqul rabbukum thoorahmatin wasiAAatin wala yuraddu ba/suhuAAani alqawmi almujrimeen

So if they deny you, [O Muḥammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals."

Then, if they give the lie to you, say, “Your Lord is the Lord of all-embracing mercy, and His punishment cannot be averted from the sinning people.”
