The word(s) "sedition" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) 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).

(2) Verily, they had plotted sedition before, and had upset matters for you, until the truth (victory) came and the Decree of Allah (His religion, Islam) became manifest though they hated it.
