The word(s) "unseen" appears 42 time(s) in 42 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) 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.

(22) 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.

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

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

(25) The Knower of the unseen and the seen, so may He be exalted above what they associate (with Him).

(26) Say: No one in the heavens and the earth knows the unseen but Allah; and they do not know when they shall be raised.

(27) This is the Knower of the unseen and the seen, the Mighty the Merciful,

(28) And those who disbelieve say: The hour shall not come upon us. Say: Yea! by my Lord, the Knower of the unseen, it shall certainly come upon you; not the weight of an atom becomes absent from Him, in the heavens or in the earth, and neither less than that nor greater, but (all) is in a clear book

(29) But when We decreed death for him, naught showed them his death but a creature of the earth that ate away his staff; and when it fell down, the jinn came to know plainly that if they had known the unseen, they would not have tarried in abasing torment.

(30) Say: Surely my Lord utters the truth, the great Knower of the unseen.
