The word(s) "ruin" appears 21 time(s) in 20 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) And who is more unjust than he who forbids that in places for the worship of Allah, Allah's name should be celebrated?-whose zeal is (in fact) to ruin them? It was not fitting that such should themselves enter them except in fear. For them there is nothing but disgrace in this world, and in the world to come, an exceeding torment.

(2) Or (take) the similitude of one who passed by a hamlet, all in ruins to its roofs. He said: "Oh! how shall Allah bring it (ever) to life, after (this) its death?" but Allah caused him to die for a hundred years, then raised him up (again). He said: "How long didst thou tarry (thus)?" He said: (Perhaps) a day or part of a day." He said: "Nay, thou hast tarried thus a hundred years; but look at thy food and thy drink; they show no signs of age; and look at thy donkey: And that We may make of thee a sign unto the people, Look further at the bones, how We bring them together and clothe them with flesh." When this was shown clearly to him, he said: "I know that Allah hath power over all things."

(3) O ye who believe! Take not into your intimacy those outside your ranks: They will not fail to corrupt you. They only desire your ruin: Rank hatred has already appeared from their mouths: What their hearts conceal is far worse. We have made plain to you the Signs, if ye have wisdom.

(4) "O my people! Enter the holy land which Allah hath assigned unto you, and turn not back ignominiously, for then will ye be overthrown, to your own ruin."

(5) And those who believe will say: "Are these the men who swore their strongest oaths by Allah, that they were with you?" All that they do will be in vain, and they will fall into (nothing but) ruin.

(6) Leave alone those who take their religion to be mere play and amusement, and are deceived by the life of this world. But proclaim (to them) this (truth): that every soul delivers itself to ruin by its own acts: it will find for itself no protector or intercessor except Allah: if it offered every ransom, (or reparation), none will be accepted: such is (the end of) those who deliver themselves to ruin by their own acts: they will have for drink (only) boiling water, and for punishment, one most grievous: for they persisted in rejecting Allah.

(7) The leaders, the unbelievers among his people, said: "If ye follow Shu'aib, be sure then ye are ruined!"

(8) The men who reject Shu'aib became as if they had never been in the homes where they had flourished: the men who rejected Shu'aib - it was they who were ruined!

(9) Did they then feel secure against the plan of Allah?- but no one can feel secure from the Plan of Allah, except those (doomed) to ruin!

(10) "As to these folk,- the cult they are in is (but) a fragment of a ruin, and vain is the (worship) which they practise."
