The Quran Verse
Surah 11:42–43:
...And Noah called to his son who was apart, 'O my son, come aboard with us and be not with the disbelievers.' said, 'I will take refuge on a mountain to protect me from the water.' ... And the waves came between them, and he was among the drowned.
The Relevant Source Text (The Bible)
Genesis 7:7, 9:18–19:
"And Noah and his sons and his wife and his sons' wives with him went into the ark to escape the waters of the flood. ... The sons of Noah who went out of the ark were Shem, Ham, and Japheth. ... These three were the sons of Noah, and from these the people of the whole earth were dispersed."
This is a major factual contradiction. The Bible is explicit that all of Noah's sons survived to repopulate the earth. The Quranic version introduces a rebellious son who drowns.
Critics argue this is a later "theological embellishment" designed to emphasize that faith—not bloodline—determines salvation. It suggests the author was either unaware of the Genesis account or intentionally altered it to create a more dramatic warning for the people of Mecca.
