Year

The triliteral root sīn nūn wāw (س ن و) occurs 20 times in the Quran, in three derived forms: once as the noun "sanā" (سَنَا), twelve times as the nominal "sinīn" (سِنِين), seven times as the noun "sanat" (سَنَة).

In The Quran

Noahs age

(29:14) We had sent Noah to his people, so he stayed with them one thousand year (Arab سَنَةٍ, sanatin) less fifty calendar years. Then the flood took them while they were wicked.

Forty years

(46:15) We instructed the human being to honor his parents. His mother bore him with hardship, gave birth to him in hardship, and his weaning lasts thirty months. Until he has attained his maturity, and reaches forty years (Arab. سَنَةً, sanatan), he says: "My Lord, expand my abilities to be thankful for the blessings You have bestowed upon me and upon my parents, and to do righteousness that pleases You. Let my progeny be righteous. I have repented to You; I am of those who have peacefully surrendered."

Day that last for years

(22:47) They seek you to hasten the retribution; and God will not break His promise. A day with your Lord is like one thousand of the years (Arab. سَنَةٍ, sanatin) you count.

(32:5) He arranges matters from the heaven to the earth, and then it ascends to Him in a day which is equivalent to one thousand of the years (Arab. سَنَةٍ, sanatin) which you count.

(70:4) The angels and the Spirit ascend to Him in a day which is equivalent to fifty Thousand years (Arab. سَنَةٍ, sanatin).

Book Of Genesis

(Genesis 9:28-29) And Noah lived after the flood three hundred and fifty years. And all the days of Noah were nine hundred years (Hebrew. שָׁנָ֔ה, šā-nāh) and fifty years (Hebrew. שָׁנָ֑ה, šā-nāh): and he died.
