Is Ibn Hazm's inference correct that Ya'rub ibn Qahtan is not a descendant of Hud (peace be upon him), based on the Almighty's saying: "And to 'Ad [We sent] their brother Hud" and "And as for 'Ad, they were destroyed by a furious, violent wind, which He imposed on them for seven nights and eight days in succession, so you would see the people therein fallen as if they were hollow trunks of palm trees. Do you then see any remnant of them?" And did any of the scholars agree with him, taking into account the saying of Hassan ibn Thabit: "We are the sons of Qahtan, and [ours is] sovereignty and glory, and among us is Allah's prophet Hud of the noble ones"?

Genealogists have differed concerning Qahtan's lineage. Al-Tabari and Ibn Khaldun mentioned that the soundest opinion is that he was the son of Abir ibn Shalikh. A number of historians have stated that Abir, to whom Qahtan is attributed, is the Prophet Hud, peace be upon him. This does not contradict the destruction of the people of Ad, because the destruction was specific to the disbelievers, while Hud and those who believed with him were saved by Allah Almighty, as in His saying: "So We saved him and those with him by Our mercy, and We cut off the root of those who denied Our signs and were not believers," and His saying: "And when Our command came, We saved Hud and those who believed with him by a mercy from Us, and We saved them from a harsh torment." So, if Hud and those who believed with him were saved, it is not far-fetched that Qahtan was among those who believed and were saved.
