Al-Anfal (The Spoils of War)
Surah 8 · Verse 25
And guard yourselves against an affliction which will not fall exclusively on those who are unjust among you, and know that Allah is severe in requiting.
Muslims are to propagate Islam 3:104 and 110. If they fail to do so, people will be deprived of right guidance and will get involved in sinful deeds for which they will be punished. The Muslims too will be involved in the punishment for not executing their duty, which too is a sin. This involvement of Muslims in punishments is seen all over the world.
