The word(s) "seen" appears 93 time(s) in 83 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) Go back to your father and say: O our father! surely your son committed theft, and we do not bear witness except to what we have known, and we could not keep watch over the unseen:

(32) This is of the announcements relating to the unseen (which) We reveal to you, and you were not with them when they resolved upon their affair, and they were devising plans.

(33) And We have not sent before you but men from (among) the people of the towns, to whom We sent revelations. Have they not then travelled in the land and seen what was the end of those before them? And certainly the abode of the hereafter is best for those who guard (against evil); do you not then understand?

(34) The knower of the unseen and the seen, the Great, the Most High.

(35) Have you not seen those who have changed Allah's favor for ungratefulness and made their people to alight into the abode of perdition

(36) And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has power over all things.

(37) Say: Allah knows best how long they remained; to Him are (known) the unseen things of the heavens and the earth; how clear His sight and how clear His hearing! There is none to be a guardian for them besides Him, and He does not make any one His associate in His Judgment.

(38) The gardens of perpetuity which the Beneficent Allah has promised to His servants while unseen; surely His promise shall come to pass.

(39) Have you, then, seen him who disbelieves in Our communications and says: I shall certainly be given wealth and children?

(40) Has he gained knowledge of the unseen, or made a covenant with the Beneficent Allah?
