The word(s) "years" appears 25 time(s) in 22 verse(s) in Quran in Muhammad Pickthal translation.

(21) And We have commended unto man kindness toward parents. His mother beareth him with reluctance, and bringeth him forth with reluctance, and the bearing of him and the weaning of him is thirty months, till, when he attaineth full strength and reacheth forty years, he saith: My Lord! Arouse me that I may give thanks for the favour wherewith Thou hast favoured me and my parents, and that I may do right acceptable unto Thee. And be gracious unto me in the matter of my seed. Lo! I have turned unto Thee repentant, and lo! I am of those who surrender (unto Thee).

(22) (Whereby) the angels and the Spirit ascend unto Him in a Day whereof the span is fifty thousand years.
