Allah the Almighty states: And to 'Ad (people, We sent) their brother Hud. He said, "O my people! Worship Allah! You have no other Ilah (god) but Him, Certainly, you do nothing but invent (lies)! 0 my people I ask of you no reward for it (the Message). My reward is only from Him Who created me. Will you not then understand? And 0 my people! Ask forgiveness of your Lord and then repent to Him, He will send you (from the sky) abundant rain, and add strength to your strength, so do not turn away as Mujrimeen (criminals, disbelievers in the Oneness of Allah)."
They said: "O Hud! No evidence have you brought us, and we shall not leave our gods for your (mere) saying! And we are not believers in you. All that we say is that some of our gods (false deities) have seized you with evil (madness)."
He said: "I call Allah to witness and bear you witness that I am free from that which you ascribe as partners in worship with Him (Allah). So plot against me, all of you, and give me no respite. I put my trust in Allah, my Lord and your Lord! There is not a moving (living) creature but He has grasp of its forelock. Verily, my Lord is on the Straight Path (the truth). So if you turn away, still I have conveyed the Message with which I was sent to you. My Lord will make another people succeed you, and you will not harm Him in the least. Surely, my Lord is Guardian over all things." Surah 11: 50-57
