And if you give [me] the lie - well, [other] communities have given the lie [to Gods prophets] before your time: but no more is an apostle bound to do than clearly deliver the message [entrusted to him]."

"And if ye reject (the Message), so did generations before you: and the duty of the apostle is only to preach publicly (and clearly)."

But if ye deny, then nations have denied before you. The messenger is only to convey (the message) plainly.

And if you reject, nations before you indeed reject (the Truth). And the duty of the Messenger is only to deliver (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.
