The word(s) "forbidden" appears 71 time(s) in 66 verse(s) in Quran in Mohsin Khan translation.

(21) 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.

(22) 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.

(23) 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."

(24) 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.

(25) 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.

(26) And they say: "What is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).

(27) Indeed lost are they who have killed their children, foolishly, without knowledge, and have forbidden that which Allah has provided for them, inventing a lie against Allah. They have indeed gone astray and were not guided.

(28) Eight pairs: of the sheep two (male and female), and of the goats two (male and female). Say: "Has He forbidden the two males or the two females, or (the young) which the wombs of the two females enclose? Inform me with knowledge if you are truthful."

(29) And of the camels two (male and female), and of oxen two (male and female). Say: "Has He forbidden the two males or the two females or (the young) which the wombs of the two females enclose? Or were you present when Allah ordered you such a thing? Then who does more wrong than one who invents a lie against Allah, to lead mankind astray without knowledge. Certainly Allah guides not the people who are Zalimun (polytheists and wrong-doers)."

(30) Say (O Muhammad صلى الله عليه وسلم): "I find not in that which has been revealed to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maitah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork); for that surely is impure or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols, or on which Allah's Name has not been mentioned while slaughtering). But whosoever is forced by necessity without wilful disobedience, nor transgressing due limits; (for him) certainly, your Lord is Oft-Forgiving, Most Merciful."
