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

(21) "Then pour over his head the torment of boiling water.

(22) The description of Paradise which the Muttaqun (the pious. See V.2:2) have been promised (is that) in it are rivers of water the taste and smell of which are not changed, rivers of milk of which the taste never changes, rivers of wine delicious to those who drink, and rivers of clarified honey (clear and pure) therein for them is every kind of fruit, and forgiveness from their Lord. (Are these) like those who shall dwell for ever in the Fire and be given to drink boiling water so that it cuts up their bowels?

(23) Those who lagged behind will say, when you set forth to take the spoils, "Allow us to follow you." They want to change Allah's Words. Say: "You shall not follow us; thus Allah has said beforehand." Then they will say: "Nay, you envy us." Nay, but they understand not except a little.

(24) And abundant spoils that they will capture. And Allah is Ever All-Mighty, All-Wise.

(25) Allah has promised you abundant spoils that you will capture, and He has hastened for you this, and He has restrained the hands of men from you: that it may be a sign for the believers, and that He may guide you to the Straight Path.

(26) Then when the heaven is rent asunder, and it becomes rosy or red like red-oil, or red hide - [See V.70:8]

(27) They will go between it (Hell) and the fierce boiling water!

(28) In fierce hot wind and boiling water,

(29) "And drink boiling water on top of it.

(30) Then for him is an entertainment with boiling water.
