In the Quran, what was the name of Noah’s son who refused to enter the Ark?

In the Quran, Noah’s son who refused to enter the Ark is unnamed.

Surah Hud describes Noah calling to his son during the flood. The son refuses to board, believing that a mountain will protect him from the water. A wave comes between them, and the son is drowned. The Quranic passage does not provide a personal name for him.

Later Islamic literature and commentary sometimes identify the son with names such as Canaan or Kanʿan, but those names are not stated in the Quranic verses themselves. This distinction matters because the question asks specifically about the Quran, not about all later traditions concerning Noah.

The Quran also emphasizes that family relationship alone does not guarantee salvation. Noah’s wife and son are presented as examples in which personal belief and conduct matter more than ancestry. The account appears in several Quranic passages, with Surah Hud providing the detailed exchange.
