The word(s) "corruption" appears 7 time(s) in 7 verse(s) in Quran in Mohsin Khan translation.

(1) And those who disbelieve are allies of one another, (and) if you (Muslims of the whole world collectively) do not do so [i.e. become allies, as one united block under one Khalifah (a chief Muslim ruler for the whole Muslim world) to make victorious Allah's religion of Islamic Monotheism], there will be Fitnah (wars, battles, polytheism) and oppression on the earth, and a great mischief and corruption (appearance of polytheism).

(2) Had they marched out with you, they would have added to you nothing except disorder, and they would have hurried about in your midst (spreading corruption) and sowing sedition among you - and there are some among you who would have listened to them. And Allah is the All-Knower of the Zalimun (polytheists and wrong-doers).

(3) "And O my people! Give full measure and weight in justice and reduce not the things that are due to the people, and do not commit mischief in the land, causing corruption.

(4) Verily, We, it is We Who have sent down the Dhikr (i.e. the Qur'an) and surely, We will guard it (from corruption) .

(5) Those who disbelieved and hinder (men) from the Path of Allah, for them We will add torment to the torment because they used to spread corruption [by disobeying Allah themselves, as well as ordering others (mankind) to do so].

(6) "And defraud not people by reducing their things, nor do evil, making corruption and mischief in the land.

(7) Verily, those who disbelieved in the Reminder (i.e. the Qur'an) when it came to them (shall receive the punishment). And verily, it is an honourable well-fortified respected Book (because it is Allah's Speech, and He has protected it from corruption. (See V.15:9)
