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

(41) Verily, those who recite the Book of Allah (this Qur'an), and perform As-Salat (Iqamat-as-Salat), and spend (in charity) out of what We have provided for them, secretly and openly, they hope for a (sure) trade-gain that will never perish.

(42) Does not man see that We have created him from Nutfah (mixed male and female sexual discharge - semen drops). Yet behold he (stands forth) as an open opponent.

(43) 'Adn (Eden) Paradise (everlasting Gardens), whose doors will be opened for them.

(44) Is he whose breast Allah has opened to Islam, so that he is in light from His Lord (as he who is a non-Muslim)? So woe to those whose hearts are hardened against remembrance of Allah! They are in plain error!
