The Prophet Hud was sent by Allah to the people of 'Ad, a powerful people who lived in the Arabian region. Despite their great strength, they were filled with pride and worshiped idols. Hud brought them the message of Allah, urging them to repent and return to the path of righteousness. However, they rejected his call, persisting in their disbelief. As a result, Allah sent a violent wind to punish them, destroying their civilization. Hud is known for his patience and perseverance in spreading the divine message despite the opposition.
