They differed concerning this son: (1) Mujahid and al-Hasan said that he was a child born of fornication, fathered by someone other than Noah, and that Noah was unaware of this. This is why He said, “that of which you have no knowledge.” Al-Hasan recited, “They both betrayed them” (al-Tahrim 10).
Abu Ja‘far al-Baqir said: He was his wife’s son, and Noah knew this; hence he said, “of my family,” rather than, “from me.”
Ibn ‘Abbas, ‘Ikrimah, Sa‘id ibn Jubayr, al-Dahhak, and the majority (3) said that he was Noah’s own son, peace be upon him. Ibn ‘Abbas said, “No prophet’s wife has ever committed adultery.” His saying, “Indeed, he is not of your family,” means: he was not among the people of your religion (4) ⦗175/b⦘, because he differed from him in religion. And His saying, “They both betrayed them,” means that they betrayed them in religion and righteous deeds, not in the marital bed.
His saying, “Indeed, I admonish you lest you be among the ignorant,” means: that you should call for the destruction of the disbelievers, then ask for the salvation of a disbeliever.
“He said, ‘My Lord, I seek refuge in You from asking You for that of which I have no knowledge. Unless You forgive me and have mercy upon me, I shall be among the losers.’ (47) It was said, ‘O Noah, disembark with peace from Us and blessings upon you and upon communities from among those with you. And there will be communities whom We shall grant enjoyment; then a painful punishment from Us will touch them.’ (48)”
Noah said, “My Lord, I seek refuge in You from asking You for that of which I have no knowledge. Unless You forgive me and have mercy upon me, I shall be among the losers.”
“It was said, ‘O Noah, disembark’”—that is, descend from the Ark—“with peace from Us,” that is, [with security and safety from Us] (5),
