وَإِن تُكَذِّبُواْ فَقَدۡ كَذَّبَ أُمَمٞ مِّن قَبۡلِكُمۡۖ وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلۡبَلَٰغُ ٱلۡمُبِينُ
Wain tukaththiboo faqad kaththaba omamun min qablikum wama AAala alrrasooli illa albalaghu almubeenu
"And if ye reject (the Message), so did generations before you: and the duty of the messenger is only to preach publicly (and clearly)."
