The word(s) "revelation" appears 70 time(s) in 67 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) And thus have We, by Our Command, sent inspiration to thee: thou knewest not (before) what was revelation, and what was Faith; but We have made the (Qur'an) a Light, wherewith We guide such of Our servants as We will; and verily thou dost guide (men) to the Straight Way,-

(52) So hold thou fast to the revelation sent down to thee; verily thou art on a Straight Way.

(53) By command, from Our Presence. For We (ever) send (revelations),

(54) The revelation of the Book is from Allah the Exalted in Power, Full of Wisdom.

(55) The revelation of the Book is from Allah the Exalted in Power, Full of Wisdom.

(56) But those who believe and work deeds of righteousness, and believe in the (revelation) sent down to Muhammad - for it is the Truth from their Lord,- He will remove from them their ills and improve their condition.

(57) That is because they hate the revelation of Allah; so He has made their deeds fruitless.

(58) They are the ones who denied revelation and hindered you from the Sacred Mosque and the sacrificial animals, detained from reaching their place of sacrifice. Had there not been believing men and believing women whom ye did not know that ye were trampling down and on whose account a crime would have accrued to you without (your) knowledge, (Allah would have allowed you to force your way, but He held back your hands) that He may admit to His Mercy whom He will. If they had been apart, We should certainly have punished the Unbelievers among them with a grievous Punishment.

(59) By the Mount (of revelation);

(60) A revelation from the Lord of the Worlds.
