24. That is, the people who had believed in Noah (peace be upon him), and who had been permitted by Allah to board the Ark. This has been elucidated in Surah Hud: Ayat 40, thus: “Until when Our command came to pass and at- Tannur began to boil up, We said, (O Noah), take into Ark a pair from every species, and embark your own people save those who have already been specifically marked, and also those who have believed; and those who had believed with Noah (peace be upon him) were only a few.”
25. It can also mean this: “We made this dreadful punishment or this great event a sign of warning for the later generations.” But from the way this has been mentioned here and in Surah Al-Qamar, it appears that the object of warning was the Ark itself, which remained on the top of the mountain for centuries and continued to remind the later generations that a flood of such magnitude had once come in that land because of which the Ark had risen up to rest on the mountain. In (Surah Al-Qamar: Ayats 13- 15), it has been said: “And We bore Noah upon a thing (Ark) made of planks and nails, which floated under Our care. This was a vengeance for the sake of him who had been slighted. And We left that Ark as a sign. Then, is there any who would take admonition?”
In his commentary on this verse of Surah Al-Qamar, Ibn Jarir says on the authority of Qatadah that during the period of the companions when the Muslims went to the land of al-Jazirah, they saw the Ark on mount Judi (according to another tradition, near the habitation of Baqirwa). In the modern times also news appear from time to time in the media that expeditions are being sent to search out the boat, because something resembling a boat has been sighted many time from airplanes during flights over Mount Ararat. See (E.N. 47 of Surah Al-Aaraf )and (E.N. 46 of Surah Hud).
