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

(201) Is it not a sign to them that the learned scholars (like 'Abdullah bin Salam رضي الله عنه who embraced Islam) of the Children of Israel knew it (as true)?

(202) "And put your hand into your bosom, it will come forth white without hurt. (These are) among the nine signs (you will take) to Fir'aun (Pharaoh) and his people. Verily they are a people who are Fasiqun (rebellious, disobedient to Allah).

(203) But when Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) came to them, clear to see, they said: "This is a manifest magic."

(204) These are their houses in utter ruin, for they did wrong. Verily, in this is indeed an Ayah (a lesson or a sign) for people who know.

(205) Nor can you lead the blind out of their error. You can only make to hear those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and who have submitted (themselves to Allah in Islam as Muslims).

(206) And (remember) the Day when We shall gather out of every nation a troop of those who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and (then) they (all) shall be driven (to the place of reckoning),

(207) Till, when they come (before their Lord at the place of reckoning), He will say: "Did you deny My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) whereas you comprehended them not by knowledge (of their truth or falsehood), or what (else) was it that you used to do?"

(208) See they not that We have made the night for them to rest therein, and the day sight-giving? Verily, in this are Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) for the people who believe.

(209) And say [(O Muhammad صلى الله عليه وسلم) to these polytheists and pagans.]: "All the praises and thanks be to Allah. He will show you His Ayat (signs, in yourselves, and in the universe or punishments), and you shall recognise them. And your Lord is not unaware of what you do."

(210) "Put your hand in your bosom, it will come forth white without a disease; and draw your hand close to your side to be free from the fear (which you suffered from the snake, and also your hand will return to its original state). These are two Burhans (signs, miracles, evidence, proofs) from your Lord to Fir'aun (Pharaoh) and his chiefs. Verily, they are the people who are Fasiqun (rebellious, disobedient to Allah).
