The word(s) "sign" appears 461 time(s) in 421 verse(s) in Quran in Abdullah Yusuf Ali translation.

(291) So naught was the answer of (Abraham's) people except that they said: "Slay him or burn him." But Allah did save him from the Fire. Verily in this are signs for people who believe.

(292) And We have left thereof an evident sign, for any people who (care to) understand.

(293) (Remember also) Qarun, Pharaoh, and Haman: there came to them Moses with Clear signs, but they behaved with insolence on the earth; yet they could not overreach (Us).

(294) Allah created the heavens and the earth in true (proportions): verily in that is a sign for those who believe.

(295) And thus (it is) that We have sent down the Book to thee. So the People of the Book believe therein, as also do some of these (pagan Arabs): and none but Unbelievers reject our signs.

(296) Nay, here are signs self-evident in the hearts of those endowed with knowledge: and none but the unjust reject Our signs.

(297) Ye they say: "Why are not signs sent down to him from his Lord?" Say: "The signs are indeed with Allah: and I am indeed a clear Warner."

(298) Do they not travel through the earth, and see what was the end of those before them? They were superior to them in strength: they tilled the soil and populated it in greater numbers than these have done: there came to them their messengers with Clear (signs). (Which they rejected, to their own destruction): It was not Allah Who wronged them, but they wronged their own souls.

(299) In the long run evil in the extreme will be the End of those who do evil; for that they rejected the signs of Allah, and held them up to ridicule.

(300) And those who have rejected Faith and falsely denied our signs and the meeting of the Hereafter,- such shall be brought forth to Punishment.
