رِجْس

Appears 9 times in the Quran. (Root: رجس)
  1. O you who believe! intoxicants and games of chance and (sacrificing to) stones set up and (dividing by) arrows are only an uncleanness, the Shaitan's work; shun it therefore that you may be successful.

  2. Therefore (for) whomsoever Allah intends that He would guide him aright, He expands his breast for Islam, and (for) whomsoever He intends that He should cause him to err, He makes his breast strait and narrow as though he were ascending upwards; thus does Allah lay uncleanness on those who do not believe.

  3. Say: I do not find in that which has been revealed to me anything forbidden for an eater to eat of except that it be what has died of itself, or blood poured forth, or flesh of swine-- for that surely is unclean-- or that which is a transgression, other than (the name of) Allah having been invoked on it; but whoever is driven to necessity, not desiring nor exceeding the limit, then surely your Lord is Forgiving, Merciful.

  4. He said: Indeed uncleanness and wrath from your Lord have lighted upon you; what! do you dispute with me about names which you and your fathers have given? Allah has not sent any authority for them; wait then, I too with you will be of those who wait.

  5. They will swear to you by Allah when you return to them so that you may turn aside from them; so do turn aside from them; surely they are unclean and their abode is hell; a recompense for what they earned.

  6. And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers.

  7. And it is not for a soul to believe except by Allah's permission; and He casts uncleanness on those who will not understand.

  8. That (shall be so); and whoever respects the sacred ordinances of Allah, it is better for him with his Lord; and the cattle are made lawful for you, except that which is recited to you, therefore avoid the uncleanness of the idols and avoid false words,

  9. And stay in your houses and do not display your finery like the displaying of the ignorance of yore; and keep up prayer, and pay the poor-rate, and obey Allah and His Messenger. Allah only desires to keep away the uncleanness from you, O people of the House! and to purify you a (thorough) purifying.
