The word(s) "necessity" appears 5 time(s) in 5 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) He hath only forbidden you dead meat, and blood, and the flesh of swine, and that on which any other name hath been invoked besides that of Allah. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits,- then is he guiltless. For Allah is Oft-forgiving Most Merciful.

(2) Why should ye not eat of (meats) on which Allah's name hath been pronounced, when He hath explained to you in detail what is forbidden to you - except under compulsion of necessity? But many do mislead (men) by their appetites unchecked by knowledge. Thy Lord knoweth best those who transgress.

(3) Say: "I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it, unless it be dead meat, or blood poured forth, or the flesh of swine,- for it is an abomination - or, what is impious, (meat) on which a name has been invoked, other than Allah's". But (even so), if a person is forced by necessity, without wilful disobedience, nor transgressing due limits,- thy Lord is Oft-forgiving, Most Merciful.

(4) And when they entered in the manner their father had enjoined, it did not profit them in the least against (the plan of) Allah: It was but a necessity of Jacob's soul, which he discharged. For he was, by our instruction, full of knowledge (and experience): but most men know not.

(5) He has only forbidden you dead meat, and blood, and the flesh of swine, and any (food) over which the name of other than Allah has been invoked. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits,- then Allah is Oft-Forgiving, Most Merciful.
