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

(1) And (remember) when We gave Musa (Moses) the Scripture [the Taurat (Torah)] and the criterion (of right and wrong) so that you may be guided aright."

(2) The month of Ramadan in which was revealed the Qur'an, a guidance for mankind and clear proofs for the guidance and the criterion (between right and wrong). So whoever of you sights (the crescent on the first night of) the month (of Ramadan i.e. is present at his home), he must observe Saum (fasts) that month, and whoever is ill or on a journey, the same number [of days which one did not observe Saum (fasts) must be made up] from other days. Allah intends for you ease, and He does not want to make things difficult for you. (He wants that you) must complete the same number (of days), and that you must magnify Allah [i.e. to say Takbir (Allahu Akbar; Allah is the Most Great] for having guided you so that you may be grateful to Him.

(3) Aforetime, as a guidance to mankind. And He sent down the criterion [of judgement between right and wrong (this Qur'an)]. Truly, those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, for them there is a severe torment; and Allah is All-Mighty, All-Able of Retribution.

(4) O you who believe! If you obey and fear Allah, He will grant you Furqan [(a criterion to judge between right and wrong), or (Makhraj, i.e. a way for you to get out from every difficulty)], and will expiate for you your sins, and forgive you; and Allah is the Owner of the Great Bounty.

(5) And know that whatever of war-booty that you may gain, verily one-fifth (1/5th) of it is assigned to Allah, and to the Messenger, and to the near relatives [of the Messenger (Muhammad صلى الله عليه وسلم)], (and also) the orphans, Al-Masakin (the poor) and the wayfarer, if you have believed in Allah and in that which We sent down to Our slave (Muhammad صلى الله عليه وسلم) on the Day of criterion (between right and wrong), the Day when the two forces met (the battle of Badr); And Allah is able to do all things.

(6) And indeed We granted to Musa (Moses) and Harun (Aaron) the criterion (of right and wrong), and a shining light [i.e. the Taurat (Torah)] and a Reminder for Al-Muttaqun (the pious - See V.2:2).

(7) Blessed be He Who sent down the criterion (of right and wrong, i.e. this Qur'an) to His slave (Muhammad صلى الله عليه وسلم) that he may be a warner to the 'Alamin (mankind and jinn).
