The word(s) "forbid" appears 104 time(s) in 89 verse(s) in Quran in Mohsin Khan translation.

(21) Why do not the rabbis and the religious learned men forbid them from uttering sinful words and from eating illegal things. Evil indeed is that which they have been performing.

(22) Surely, they have disbelieved who say: "Allah is the Messiah ['Îsa (Jesus)], son of Maryam (Mary)." But the Messiah ['Îsa (Jesus)] said: "O Children of Israel! Worship Allah, my Lord and your Lord." Verily, whosoever sets up partners (in worship) with Allah, then Allah has forbidden Paradise to him, and the Fire will be his abode . And for the Zalimun (polytheists and wrong-doers) there are no helpers.

(23) They used not to forbid one another from Al-Munkar (wrong, evil-doing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do.

(24) Those who believe and do righteous good deeds, there is no sin on them for what they ate (in the past), if they fear Allah (by keeping away from His forbidden things), and believe and do righteous good deeds, and again fear Allah and believe, and once again fear Allah and do good deeds with Ihsan (perfection). And Allah loves the good-doers.

(25) Lawful to you is (the pursuit of) water-game and its use for food - for the benefit of yourselves and those who travel, but forbidden is (the pursuit of) land-game as long as you are in a state of Ihram (for Hajj or 'Umrah). And fear Allah to Whom you shall be gathered back.

(26) O you who believe! Take care of your ownselves . If you follow the (right) guidance [and enjoin what is right (Islamic Monotheism and all that Islam orders one to do) and forbid what is wrong (polytheism, disbelief and all that Islam has forbidden)] no hurt can come to you from those who are in error. The return of you all is to Allah, then He will inform you about (all) that which you used to do.

(27) Nay, it has become manifest to them what they had been concealing before. But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars.

(28) Say (O Muhammad صلى الله عليه وسلم): "I have been forbidden to worship those whom you invoke (worship) besides Allah." Say: "I will not follow your vain desires. If I did, I would go astray, and I would not be one of the rightly guided."

(29) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.

(30) And according to their claim, they say that such and such cattle and crops are forbidden, and none should eat of them except those whom we allow. And (they say) there are cattle forbidden to be used for burden (or any other work), and cattle on which (at slaughtering) the Name of Allah is not pronounced; lying against Him (Allah). He will recompense them for what they used to fabricate.
