Did Noah (peace be upon him) live for 950 years, and why is it mentioned in the Quran that he lived for a thousand years save fifty years, distinguishing between "sanah" (year) and "ʿām" (year)?

In the age of Noah (peace be upon him) there is a profound lesson and admonition. He spent long centuries calling his people to God without despair, which teaches preachers patience and determination. His life also reminds humans that death is coming and that life is an opportunity to attain eternal happiness. It was narrated on the authority of Anas ibn Malik (may Allah be pleased with him) that the Angel of Death asked Noah (peace be upon him) how he found the world, and he replied: "Like a man who entered a house with two doors, stood in the middle of the house for a while, then exited through the other door."

There is nothing definitive in the explicit Quran and Sunnah about specifying the age of Noah (peace be upon him). However, there are sayings from early scholars, including: 1. 950 years: The saying of Qatadah, who lived among them for 300 years before calling them, called them for 300 years, and lived 350 years after the flood. 2. 1050 years: The saying of Ibn Abbas, who was sent as a prophet at the age of forty, called them for one thousand years minus fifty years, and lived sixty years after the flood. 3. 1020 years: The saying of Ka'b al-Ahbar, who lived seventy years after the flood. 4. 1400 years: Narrated from Ibn Abbas and Wahb ibn Munabbih. 5. 1650 years: The saying of Awn ibn Abi Shaddad, who was sent as a prophet at the age of 350 years, called them for 950 years, and lived 350 years after that. 6. 1700 years: The saying of Ikrimah, before he was sent as a prophet and after he was sent.

As for the difference between the word "sanah" (سنة - year) and "aam" (عام - year), there are two opinions: 1. Linguistic wisdom: To avoid repeating the same word and its heaviness on the tongue, so a synonymous, different word was used to achieve lightness. 2. Semantic wisdom: The use of "sanah" to denote the difficulty of the years of calling and drought, while "aam" denotes the years of prosperity and abundance after the flood. Some scholars have combined both types of wisdom, the linguistic and the semantic.
