Allah the Almighty states: And to 'Ad (people, We sent) their brother Hud. He said, "0 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: "0 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
Hud (PUBH) Explains the Day of Judgment
Hud tried to speak to them and to explain about Allah's blessings: how Allah the Almighty had made them Noah's successors, how He had given them strength and power, and how He sent them rain to revive the soil.
Hud's people looked about them and found they were the strongest on earth, so they became prouder and more obstinate. Thus they argued a lot with Hud. They asked: "0 Hud! Do you say that after we die and turn into dust, we will be resurrected?" He replied: 'Yes, you will come back on the Day of Judgment and each one of you will be asked about what you did."
A peal of laughter was heard after the last statement. "How strange Hud's claims are!" The disbelievers muttered among themselves. They believed that when man dies his body decays and turns into dust which is swept away by the wind. How could that return to its original state? Then what is the significance of the Day of Judgment? Why do the dead return to life?
All these questions were patiently received by Hud. He then addressed his people concerning the Day of Judgment. He explained that belief in the Day of Judgment is essential to Allah's justice, teaching them the same thing that every prophet taught about it.
Hud explained that justice demands that there be a Day of Judgment because good is not always victorious in life. Sometimes evil overpowers good. Will such crimes go unpunished? If we suppose there is no Day of Judgment, then a great injustice will have prevailed, but Allah has forbidden injustice to be incurred by Himself or His subjects. Therefore, the existence of the Day of Judgment, a day of accounting for our deeds and being rewarded or punished for them, reveals the extent of Allah's justice. Hud spoke to them about all of these things. They listened but disbelieved him.
