The word(s) "oil" appears 40 time(s) in 34 verse(s) in Quran in Mohsin Khan translation.

(11) And a tree (olive) that springs forth from Mount Sinai, that grows (produces) oil, and (it is a) relish for the eaters.

(12) Allah is the Light of the heavens and the earth. The parable of His Light is as (if there were) a niche and within it a lamp: the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east (i.e. neither it gets sun-rays only in the morning) nor of the west (i.e. nor it gets sun-rays only in the afternoon, but it is exposed to the sun all day long), whose oil would almost glow forth (of itself), though no fire touched it. Light upon Light! Allah guides to His Light whom He wills. And Allah sets forth parables for mankind, and Allah is All-Knower of everything.

(13) She said: "Verily kings, when they enter a town (country), they despoil it and make the most honourable amongst its people the lowest. And thus they do.

(14) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(15) Who, out of His Grace, has lodged us in a home that will last forever, where toil will touch us not nor weariness will touch us."

(16) Then on the top of that they will be given boiling water to drink so that it becomes a mixture (of boiling water and Zaqqum in their bellies).

(17) This is so! Then let them taste it - a boiling fluid and dirty wound discharges.

(18) In the boiling water, then they will be burned in the Fire.

(19) Like boiling oil, it will boil in the bellies,

(20) Like the boiling of scalding water.
