Translation of the verse 18 from Surah Al-‘Ankabut : Number of verses 69 - - page 398 - Part 20.
"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."
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.
(29:18) And if you give the lie (to the Messenger), then many nations before you also gave the lie *30 (to their Messengers). The Messenger is charged with no other duty than to deliver the Message in clear terms.'
*30) That is, "If you reject my invitation to Tauhid and deny my message that you have to return to your Lord and render an account of your deeds, it will not be a new thing. In the history of mankind many Prophets-like Noah, Hud, Salih (on whom be Allah's peace) before also have brought the same teachings, and their peoples denied them likewise. Now you may judge for yourselves as to whether they harmed the Prophets or only themselves" .
