The word(s) "forbidden" appears 37 time(s) in 35 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) Those who are polytheists will say: If Allah had pleased we would not have associated (aught with Him) nor our fathers, nor would we have forbidden (to ourselves) anything; even so did those before them reject until they tasted Our punishment. Say: Have you any knowledge with you so you should bring it forth to us? You only follow a conjecture and you only tell lies.

(22) Say: Bring your witnesses who should bear witness that Allah has forbidden this, then if they bear witness, do not bear witness with them; and follow not the low desires of those who reject Our communications and of those who do not believe in the hereafter, and they make (others) equal to their Lord.

(23) Say: Come I will recite what your Lord has forbidden to you-- (remember) that you do not associate anything with Him and show kindness to your parents, and do not slay your children for (fear of) poverty-- We provide for you and for them-- and do not draw nigh to indecencies, those of them which are apparent and those which are concealed, and do not kill the soul which Allah has forbidden except for the requirements of justice; this He has enjoined you with that you may understand.

(24) But the Shaitan made an evil suggestion to them that he might make manifest to them what had been hidden from them of their evil inclinations, and he said: Your Lord has not forbidden you this tree except that you may not both become two angels or that you may (not) become of the immortals.

(25) Therefore when they revoltingly persisted in what they had been forbidden, We said to them: Be (as) apes, despised and hated.

(26) But why were there not among the generations before you those possessing understanding, who should have forbidden the making of mischief in the earth, except a few of those whom We delivered from among them? And those who were unjust went after what they are made to enjoy of plenty, and they were guilty.

(27) They said: Have we not forbidden you from (other) people?

(28) He has only forbidden you what dies of itself and blood and flesh of swine and that over which any other name than that of Allah has been invoked, but whoever is driven to necessity, not desiring nor exceeding the limit, then surely Allah is Forgiving, Merciful.

(29) And do not kill any one whom Allah has forbidden, except for a just cause, and whoever is slain unjustly, We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.

(30) The fornicator shall not marry any but a fornicatress or idolatress, and (as for) the fornicatress, none shall marry her but a fornicator or an idolater; and it is forbidden to the believers.
