Al-'Ankabut 29:18

وَإِن تُكَذِّبُوا۟ فَقَدْ كَذَّبَ أُمَمٌ مِّن قَبْلِكُمْ ۖ وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلْبَلَـٰغُ ٱلْمُبِينُ

Wa-in tukadhibū faqad kadhaba umamun min qablikum wamā ʿalā l-rasūli illā l-balāghu l-mubīnu

And if you [people] deny [the message] - already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification.
