The word(s) "sign" appears 181 time(s) in 162 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) I will turn away from My communications those who are unjustly proud in the earth; and if they see every sign they will not believe in It; and if they see the way of rectitude they do not take It for a way, and if they see the way of error. they take it for a way; this is because they rejected Our communications and were heedless of them.

(32) He it is Who made the sun a shining brightness and the moon a light, and ordained for it mansions that you might know the computation of years and the reckoning. Allah did not create it but with truth; He makes the signs manifest for a people who know.

(33) Most surely in the variation of the night and the day, and what Allah has created in the heavens and the earth, there are signs for a people who guard (against evil).

(34) And they say: Why is not a sign sent to him from his Lord? Say: The unseen is only for Allah; therefore wait-- surely I too, with you am of those who wait.

(35) He it is Who made for you the night that you might rest in it, and the day giving light; most surely there are signs in it for a people who would hear.

(36) Then did We send up after them Musa and Haroun to Firon and his chiefs with Our signs, but they showed pride and they were a guilty people.

(37) But We will this day deliver you with your body that you may be a sign to those after you, and most surely the majority of the people are heedless to Our communications.

(38) Though every sign should come to them, until they witness the painful chastisement.

(39) Say: Consider what is it that is in the heavens and the earth; and signs and warners do not avail a people who would not believe.

(40) And, O my people! this will be (as) Allah's she-camel for you, a sign; therefore leave her to pasture on Allah's earth and do not touch her with evil, for then a near chastisement will overtake you.
