ARK, NOAH’S نوح فلك.
It is mentioned in the history of the Deluge, as recorded in the Qur’an, in two places – Surah xi. 39, “Build the ark under our eye and after our revelation,” and Surah xiii 27. “There is also supposed to be an allusion to the ark in Surah lxxvi. 41. “And a sign to them is that we bare their offspring in the laden ship.”
Al- Baizawi says that Noah was two years building the ark, which was 300 cubits long, 50 wide, and 30 bread which was made of Indian plane-tree; that it consisted of three storeys, the lowest for beasts, the middle for men and women (who were separated from each other), and the highest for birds.
The ark is said to have rested on the mountain al-Judi.
