The word(s) "sign" appears 351 time(s) in 320 verse(s) in Quran in Mohsin Khan translation.

(221) Nay, but they, the clear Ayat [i.e. the description and the qualities of Prophet Muhammad صلى الله عليه وسلم written in the Taurat (Torah) and the Injeel (Gospel)] are preserved in the breasts of those who have been given knowledge (among the people of the Scriptures). And none but the Zalimun (polytheists and wrongdoers) deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(222) And they say: "Why are not signs sent down to him from his Lord? Say: "The signs are only with Allah, and I am only a plain warner."

(223) Then evil was the end of those who did evil, because they belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, Messengers, etc.) of Allah and made a mockery of them.

(224) And as for those who disbelieved and belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, Allah's Messengers, Resurrection, etc.), and the Meeting of the Hereafter, such shall be brought forth to the torment (in the Hell-fire).

(225) And among His signs is this, that He created you (Adam) from dust, and then [Hawwa' (Eve) from Adam's rib, and then his offspring from the semen, and], - behold you are human beings scattered!

(226) And among His signs is this, that He created for you wives from among yourselves, that you may find repose in them, and He has put between you affection and mercy. Verily, in that are indeed signs for a people who reflect.

(227) And among His signs is the creation of the heavens and the earth, and the difference of your languages and colours. Verily, in that are indeed signs for men of sound knowledge.

(228) And among His signs is your sleep by night and by day, and your seeking of His Bounty. Verily, in that are indeed signs for a people who listen.

(229) And among His signs is that He shows you the lightning, for fear and for hope, and He sends down water (rain) from the sky, and therewith revives the earth after its death. Verily, in that are indeed signs for a people who understand.

(230) And among His signs is that the heaven and the earth stand by His Command. Then afterwards when He will call you by a single call, behold, you will come out from the earth (i.e. from your graves for reckoning and recompense).
