The word(s) "ruin" appears 28 time(s) in 28 verse(s) in Quran in Muhammad Pickthal translation.

(1) And who doth greater wrong than he who forbiddeth the approach to the sanctuaries of Allah lest His name should be mentioned therein, and striveth for their ruin. As for such, it was never meant that they should enter them except in fear. Theirs in the world is ignominy and theirs in the Hereafter is an awful doom.

(2) Spend your wealth for the cause of Allah, and be not cast by your own hands to ruin; and do good. Lo! Allah loveth the beneficent.

(3) Or (bethink thee of) the like of him who, passing by a township which had fallen into utter ruin, exclaimed: How shall Allah give this township life after its death? And Allah made him die a hundred years, then brought him back to life. He said: How long hast thou tarried? (The man) said: I have tarried a day or part of a day. (He) said: Nay, but thou hast tarried for a hundred years. Just look at thy food and drink which have not rotted! Look at thine ass! And, that We may make thee a token unto mankind, look at the bones, how We adjust them and then cover them with flesh! And when (the matter) became clear unto him, he said: I know now that Allah is Able to do all things.

(4) O ye who believe! Take not for intimates others than your own folk, who would spare no pains to ruin you; they love to hamper you. Hatred is revealed by (the utterance of) their mouths, but that which their breasts hide is greater. We have made plain for you the revelations if ye will understand.

(5) Say: Unto whom belongeth whatsoever is in the heavens and the earth? Say: Unto Allah. He hath prescribed for Himself mercy, that He may bring you all together to the Day of Resurrection whereof there is no doubt. Those who ruin their souls will not believe.

(6) Those unto whom We gave the Scripture recognise (this revelation) as they recognise their sons. Those who ruin their own souls will not believe.

(7) And they forbid (men) from it and avoid it, and they ruin none save themselves, though they perceive not.

(8) Thus have their (so-called) partners (of Allah) made the killing of their children to seem fair unto many of the idolaters, that they may ruin them and make their faith obscure for them. Had Allah willed (it otherwise), they had not done so. So leave them alone with their devices.

(9) We wronged them not, but they did wrong themselves; and their gods on whom they call beside Allah availed them naught when came thy Lord's command; they added to them naught save ruin.

(10) They said: By Allah, thou wilt never cease remembering Joseph till thy health is ruined or thou art of those who perish!
