One of the most blessed trees mentioned in the Qur'an and sunnah. Allah SWT gave it a beautiful status in Al Noor, verse 35:
Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a pearly [white] star lit from [the oil of] a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allah guides to His light whom He wills. And Allah presents examples for the people, and Allah is Knowing of all things.
Al Mu'minun, verse 20:
And a tree (olive) that springs forth from Mount Sinai, that grows oil, and (it is a) relish for the eatersM.
Al An'aam, verse 99 and 141:
And it is He who sends down rain from the sky, and We produce thereby the growth of all things. We produce from it greenery from which We produce grains arranged in layers. And from the palm trees - of its emerging fruit are clusters hanging low. And [We produce] gardens of grapevines and olives and pomegranates, similar yet varied. Look at [each of] its fruit when it yields and [at] its ripening. Indeed in that are signs for a people who believe.
And He it is who causes gardens to grow, [both] trellised and untrellised, and palm trees and crops of different [kinds of] food and olives and pomegranates, similar and dissimilar. Eat of [each of] its fruit when it yields and give its due [zakah] on the day of its harvest. And be not excessive. Indeed, He does not like those who commit excess.
At Tin, verse 1-3:
By the fig, and the olive,
And [by] Mount Sinai
And by this city of security (Makkah).
