It is also reported that Kin’aan climbed up a high mountain, hid in a cave and sealed every opening of the cave. But when the wave of flood struck the top of the mountain, the cave filled with water. In this way, Kin’aan drowned into dirty water containing his excreta.
(Iafseer As-Saawi, vol. 3, pp. 914; Part 12, Surah Hood, Ayah 43)
Allah has mentioned about this event in the Holy Quran:
And Nuh called out to his son and he was standing aside from it (outside the Ark), ‘O my son! Embark along with us, and do not be with the disbelievers.’ He (the son) said, ‘I shall seek refuge on a mountain, which will save me from the water.’ Nuh said, ‘Today there is no one who can save you from the punishment of Allah, except upon whom He bestows mercy,’ and the wave came in between them, so he remained amongst the drowning ones.
[Kanz-ul-Iman (Translation of Quran)] (Part 12, Surah Hood, Ayah 42-43)
Seeing his son drowning in front of his eyes, Sayyiduna Nuh became very grievous and sad. He implored Allah , ‘O my Rab! My son, Kin’ aan is among my household and Your promise is true. You are [Ahkam-ul-Hakimeen].’ Allah said in reply, ‘O Nuh! Your son, Kin’ aan is not among those households of yours about whom I promised to save. Therefore, 0 Nuh! Your request is not valid, so request me not of any such thing about which you are not aware of.’ Sayyiduna Nuh said, ‘O Allah ! I seek Your refuge from asking You of any such thing that I am not aware of and if
You do not shower Your mercy upon me by forgiving me, then I will be at loss.’ (Iafseer As-Saawi, vol. 3, pp. 915-916, summarized; part 12, Surah Hood, Ayah 45-47)
Describing this parable, Allah has mentioned in the Holy Quran:
And Nuh prayed to his Lord; requesting, ‘O My Lord! Indeed my son is also from my family, and surely Your promise is true and You are The Greatest of all in Commanding.’ He (Allah) said, ‘O Nuh, he is not from your family; his deeds are most despicable; do not ask Me for that of which you have no knowledge (in this regard); I advise you not to become oblivious.’ He submitted, ‘O My Lord! I seek your refuge from asking you that of which I have no knowledge, and if You do not forgive me and do not have mercy upon me, then I would he a loser.’
[Kanz-ul-Iman (Translation of Quran)J (Part 12, Surah Hood, Ayah 45-47)
