warner
in Edition Clear Qur'an by Talal Itani / Saba (Sheba)

34:28We sent you only universally to all people, a herald and warner, but most people do not know.

34:34We sent no warner to any town, without its affluent saying, “We reject what you are sent with.”

34:44But We gave them no book to study, and We did not send them any warner before you.

34:46Say, “I offer you a single advice: devote yourselves to God, in pairs, or individually; and reflect. There is no madness in your friend. He is just a warner to you, before the advent of a severe punishment.”
