The word(s) "ark" appears 59 time(s) in 57 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) He it is Who sends His blessings on you, and (so do) His angels, that He may bring you forth out of utter darkness into the light; and He is Merciful to the believers.

(42) Nor the darkness and the light,

(43) And a sign to them is the night: We draw forth from it the day, then lo! they are in the dark;

(44) He has created you from a single being, then made its mate of the same (kind), and He has made for you eight of the cattle in pairs. He creates you in the wombs of your mothers-- a creation after a creation-- in triple darkness; that is Allah your Lord, His is the kingdom; there is no god but He; whence are you then turned away?

(45) Hearken to your Lord before there comes the day from Allah for which there shall be no averting; you shall have no refuge on that day, nor shall it be yours to make a denial.

(46) And if We please We would have made you know them so that you would certainly have recognized them by their marks and most certainly you can recognize them by the intent of (their) speech; and Allah knows your deeds.

(47) Muhammad is the Apostle of Allah, and those with him are firm of heart against the unbelievers, compassionate among themselves; you will see them bowing down, prostrating themselves, seeking grace from Allah and pleasure; their marks are in their faces because of the effect of prostration; that is their description in the Taurat and their description in the Injeel; like as seed-produce that puts forth its sprout, then strengthens it, so it becomes stout and stands firmly on its stem, delighting the sowers that He may enrage the unbelievers on account of them; Allah has promised those among them who believe and do good, forgiveness and a great reward.

(48) The guilty shall be recognized by their marks, so they shall be seized by the forelocks and the feet.

(49) He it is who sends down clear communications upon His servant, that he may bring you forth from utter darkness into light; and most surely Allah is Kind, Merciful to you.

(50) An Apostle who recites to you the clear communications of Allah so that he may bring forth those who believe and do good deeds from darkness into light; and whoever believes in Allah and does good deeds, He will cause him to enter gardens beneath which rivers now, to abide therein forever, Allah has indeed given him a goodly sustenance.
