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

(301) And in Musa (Moses) (too, there is a sign), when We sent him to Fir'aun (Pharaoh) with a manifest authority.

(302) And in 'Ad (there is also a sign) when We sent against them the barren wind;

(303) And in Thamud (there is also a sign), when they were told: "Enjoy yourselves for a while!"

(304) Indeed he (Muhammad صلى الله عليه وسلم) did see of the Greatest signs, of his Lord (Allah).

(305) And if they see a sign, they turn away, and say: "This is continuous magic."

(306) And indeed, We have left this as a sign. Then is there any that will remember (or receive admonition)?

(307) (They) belied all Our signs, so We seized them with a Seizure of the All-Mighty, All-Capable (Omnipotent).

(308) It is He Who sends down manifest Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to His slave (Muhammad صلى الله عليه وسلم) that He may bring you out from darkness into light. And verily, Allah is to you full of kindness, Most Merciful.

(309) Know that Allah gives life to the earth after its death! Indeed We have made clear the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to you, if you but understand.

(310) And those who believe in (the Oneness of) Allah and His Messengers - they are the Siddiqun (i.e. those followers of the Prophets who were first and foremost to believe in them), and the martyrs with their Lord, they shall have their reward and their light. But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) and deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - they shall be the dwellers of the blazing Fire.
