And to 'Ad (people, We sent) their brother Hud. He said: "O my people! Worship Allah! You have no other Ilah (God) but Him. (La ilaha ill-Allah: none has the right to be worshipped but Allah). Will you not fear (Allah)?"

The leaders of those who disbelieved among his people said: "Verily, we see you in foolishness, and verily, we think you are one of the liars."

(Hud) said: "O my people! There is no foolishness in me, but (I am) a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists)!

"I convey unto you the Messages of my Lord, and I am a trustworthy adviser (or well-wisher) for you.

"Do you wonder that there has come to you a Reminder (and an advice) from your Lord through a man from amongst you that he may warn you? And remember that He made you successors after the people of Nuh (Noah), and increased you amply in stature. So remember the graces (bestowed upon you) from Allah, so that you may be successful."

They said: "You have come to us that we should worship Allah Alone and forsake that which our fathers used to worship. So bring us that wherewith you have threatened us if you are of the truthful."

(Hud) said: "Torment and wrath have already fallen on you from your Lord. Dispute you with me over names which you have named - you and your fathers, with no authority from Allah? Then wait, I am with you among those who wait."

So We saved him and those who were with him by a Mercy from Us, and We cut the roots of those who belied Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), and they were not believers.
