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

(11) forbidden to you (for marriage) are: your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your foster mother who gave you suck, your foster milk suckling sisters, your wives' mothers, your step daughters under your guardianship, born of your wives to whom you have gone in - but there is no sin on you if you have not gone in them (to marry their daughters), - the wives of your sons who (spring) from your own loins, and two sisters in wedlock at the same time, except for what has already passed; verily, Allah is Oft-Forgiving, Most Merciful.

(12) Also (forbidden are) women already married, except those (slaves) whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek (them in marriage) with Mahr (bridal-money given by the husband to his wife at the time of marriage) from your property, desiring chastity, not committing illegal sexual intercourse, so with those of whom you have enjoyed sexual relations, give them their Mahr as prescribed; but if after a Mahr is prescribed, you agree mutually (to give more), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise.

(13) If you avoid the great sins which you are forbidden to do, We shall expiate from you your (small) sins, and admit you to a Noble Entrance (i.e. Paradise).

(14) And their taking of Riba (usury) though they were forbidden from taking it and their devouring of men's substance wrongfully (bribery). And We have prepared for the disbelievers among them a painful torment.

(15) forbidden to you (for food) are: Al-Maitah (the dead animals - cattle - beast not slaughtered), blood, the flesh of swine, and that on which Allah's Name has not been mentioned while slaughtering, (that which has been slaughtered as a sacrifice for others than Allah, or has been slaughtered for idols) and that which has been killed by strangling, or by a violent blow, or by a headlong fall, or by the goring of horns - and that which has been (partly) eaten by a wild animal - unless you are able to slaughter it (before its death) - and that which is sacrificed (slaughtered) on An-Nusub (stone-altars). (forbidden) also is to use arrows seeking luck or decision; (all) that is Fisqun (disobedience of Allah and sin). This day, those who disbelieved have given up all hope of your religion; so fear them not, but fear Me. This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion. But as for him who is forced by severe hunger, with no inclination to sin (such can eat these above mentioned meats), then surely, Allah is Oft-Forgiving, Most Merciful.

(16) (Allah) said: "Therefore it (this holy land) is forbidden to them for forty years; in distraction they will wander through the land. So be not sorrowful over the people who are the Fasiqun (rebellious and disobedient to Allah)."

(17) (They like to) listen to falsehood, to devour anything forbidden. So if they come to you (O Muhammad صلى الله عليه وسلم), either judge between them, or turn away from them. If you turn away from them, they cannot hurt you in the least. And if you judge, judge with justice between them. Verily, Allah loves those who act justly.

(18) 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.

(19) 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.

(20) 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.
