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

(241) Is it not a guidance for them: how many generations We have destroyed before them in whose dwellings they do walk about? Verily, therein indeed are signs. Would they not then listen?

(242) But those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to frustrate them - those, for them will be a severe painful torment.

(243) See they not what is before them and what is behind them, of the heaven and the earth? If We will, We shall sink the earth with them, or cause a piece of the heaven to fall upon them. Verily, in this is a sign for every slave who turns to Allah in repentance (i.e. the one who believes in the Oneness of Allah and performs deeds of His obedience and always begs His Pardon).

(244) Indeed there was for Saba' (Sheba) a sign in their dwelling-place - two gardens on the right hand and on the left; (and it was said to them:) "Eat of the provision of your Lord, and be grateful to Him." A fair land and an Oft-Forgiving Lord!

(245) But they said: "Our Lord! Make the stages between our journey longer," and they wronged themselves; so We made them as tales (in the land), and We dispersed them all totally. Verily, in this are indeed signs for every steadfast, grateful (person).

(246) And those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), to frustrate them, they will be brought to the torment.

(247) And when Our Clear Verses are recited to them, they say: "This (Muhammad صلى الله عليه وسلم) is naught but a man who wishes to hinder you from that which your fathers used to worship." And they say: "This (the Qur'an) is nothing but an invented lie." And those who disbelieve say of the truth when it has come to them (i.e. Prophet Muhammad صلى الله عليه وسلم when Allah sent him as a Messenger with proofs, evidence, verses of this Qur'an, lessons, signs, etc.): "This is nothing but evident magic!"

(248) And if they belie you, those before them also belied. Their Messengers came to them with clear signs, and with the Scriptures, and the book giving light.

(249) And a sign for them is the dead land. We give it life, and We bring forth from it grains, so that they eat thereof.

(250) And a sign for them is the night. We withdraw therefrom the day, and behold, they are in darkness.
