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.
— Saheeh International
If you say this is a lie, [be warned that] other communities before you said the same. The messenger’s only duty is to give clear warning.’
— M. A. S. Abdel Haleem
"And if you deny, then nations before you have denied (their Messengers). And the duty of the Messenger is only to convey (the Message) plainly."
