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

(191) He has made subject to you the Night and the Day; the sun and the moon; and the stars are in subjection by His Command: verily in this are signs for men who are wise.

(192) And the things on this earth which He has multiplied in varying colours (and qualities): verily in this is a sign for men who celebrate the praises of Allah (in gratitude).

(193) And marks and sign-posts; and by the stars (men) guide themselves.

(194) (We sent them) with Clear signs and Books of dark prophecies; and We have sent down unto thee (also) the Message; that thou mayest explain clearly to men what is sent for them, and that they may give thought.

(195) And they (even) assign, to things they do not know, a portion out of that which We have bestowed for their sustenance! By Allah, ye shall certainly be called to account for your false inventions.

(196) And they assign daughters for Allah! - Glory be to Him! - and for themselves (sons,- the issue) they desire!

(198) And verily in cattle (too) will ye find an instructive sign. From what is within their bodies between excretions and blood, We produce, for your drink, milk, pure and agreeable to those who drink it.

(199) And from the fruit of the date-palm and the vine, ye get out wholesome drink and food: behold, in this also is a sign for those who are wise.
