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

(271) Is it not a sign to them that the Learned of the Children of Israel knew it (as true)?

(272) "Now put thy hand into thy bosom, and it will come forth white without stain (or harm): (these are) among the nine signs (thou wilt take) to Pharaoh and his people: for they are a people rebellious in transgression."

(273) But when Our signs came to them, that should have opened their eyes, they said: "This is sorcery manifest!"

(274) And they rejected those signs in iniquity and arrogance, though their souls were convinced thereof: so see what was the end of those who acted corruptly!

(275) Now such were their houses, - in utter ruin, - because they practised wrong-doing. Verily in this is a sign for people of knowledge.

(276) Nor canst thou be a guide to the blind, (to prevent them) from straying: only those wilt thou get to listen who believe in Our signs, and they will bow in Islam.

(277) And when the Word is fulfilled against them (the unjust), we shall produce from the earth a beast to (face) them: He will speak to them, for that mankind did not believe with assurance in Our signs.

(278) One day We shall gather together from every people a troop of those who reject our signs, and they shall be kept in ranks,-

(279) Until, when they come (before the Judgment-seat), (Allah) will say: "Did ye reject My signs, though ye comprehended them not in knowledge, or what was it ye did?"

(280) See they not that We have made the Night for them to rest in and the Day to give them light? Verily in this are signs for any people that believe!
