The word(s) "sign" appears 56 time(s) in 52 verse(s) in Quran in Muhammad Pickthal translation.

(41) There was indeed a sign for Sheba in their dwelling-place: Two gardens on the right hand and the left (as who should say): Eat of the provision of your Lord and render thanks to Him. A fair land and an indulgent Lord!

(42) And they designed a snare for him, but We made them the undermost.

(43) The chiefs among them go about, exhorting: Go and be staunch to your gods! Lo! this is a thing designed.

(44) And though they are resigned, yet the Fire is still their home; and if they ask for favour, yet they are not of those unto whom favour can be shown.

(45) And We assigned them comrades (in the world), who made their present and their past fairseeming unto them. And the Word concerning nations of the jinn and humankind who passed away before them hath effect for them. Lo! they were ever losers.

(46) If He will He calmeth the wind so that they keep still upon its surface - Lo! herein verily are signs for every steadfast grateful (heart). -

(47) And he whose sight is dim to the remembrance of the Beneficent, We assign unto him a devil who becometh his comrade;

(48) And verily We had empowered them with that wherewith We have not empowered you, and had assigned them ears and eyes and hearts; but their ears and eyes and hearts availed them naught since they denied the revelations of Allah; and what they used to mock befell them.

(49) Lo! We have given thee (O Muhammad) a signal victory,

(50) Say (unto them, O Muhammad): He it is who gave you being, and hath assigned unto you ears and eyes and hearts. Small thanks give ye!
