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
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.’
"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."
