The word(s) "open" appears 56 time(s) in 55 verse(s) in Quran in Mohsin Khan translation.

(21) And when they opened their bags, they found their money had been returned to them. They said: "O our father! What (more) can we desire? This, our money has been returned to us; so we shall get (more) food for our family, and we shall guard our brother and add one more measure of a camel's load. This quantity is easy (for the king to give)."

(22) It is the same (to Him) whether any of you conceal his speech or declares it openly, whether he be hid by night or goes forth freely by day.

(23) And those who remain patient, seeking their Lord's Countenance, perform As-Salat (Iqamat-as-Salat), and spend out of that which We have bestowed on them, secretly and openly, and defend evil with good, for such there is a good end.

(24) Say (O Muhammad صلى الله عليه و سلم) to 'Ibadi (My slaves) who have believed, that they should perform As-Salat (Iqamat-as-Salat ), and spend in charity out of the sustenance We have given them, secretly and openly, before the coming of a Day on which there will be neither mutual bargaining nor befriending.

(25) And even if We opened to them a gate from the heaven and they were to keep on ascending thereto (all the day long)

(26) So, We took vengeance on them. They are both on an open highway, plain to see.

(27) Therefore proclaim openly (Allah's Message - Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(28) He has created man from Nutfah (mixed drops of male and female sexual discharge), then behold, this same (man) becomes an open opponent.

(29) Allah puts forward the example of (two men - a believer and a disbeliever); a slave (disbeliever) under the possession of another, he has no power of any sort, and (the other), a man (believer) on whom We have bestowed a good provision from Us, and he spends thereof secretly and openly. Can they be equal? (By no means). All the praises and thanks are to Allah. Nay! (But) most of them know not.

(30) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.
