نوح
Nuh AS was a prophet and, as the Prophet ﷺ said, the first messenger. After calling his people for 950 years he prayed that no disbeliever be left on earth, and Allah destroyed all but the believers with him; Allah had taught him to build the ship. One of his sons was a disbeliever, showing that faith does not pass automatically from father to child. On the Day of Judgment he will excuse himself from intercession for having asked Allah to save that son. The Prophet ﷺ likened the firmness of Umar RA to Nuh AS and Musa AS. By tradition his three sons Sam, Ham and Yafith are the ancestors of the nations, supported by a weak hadith in al-Tirmidhi.
