The Prophet continued preaching to the Arabs in a most gentle and reasonable manner. He called the people, so accustomed to iniquity and wrong-doings, to abandon their abominations. In burning words which excited the hearts of his hearers, he warned them of the punishment which Allah had inflicted upon the ancient tribes of 'Ad and Thamud who had obstinately disobeyed the teachings of Allah's messengers to them. He adjured them by the wonderful sights of nature, by the noonday brightness, by the night when it spreads its veil, by the day when it appears in glory to listen to his warning before a similar destruction befell them. He spoke to them of the Day of Reckoning, when their deeds in this world will be weighed before the Eternal Judge, when the children who had been buried alive will be asked for what crime they were put to death.
