The word(s) "prison" appears 15 time(s) in 15 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And he raised his parents upon the throne and they fell down in prostration before him, and he said: O my father! this is the significance of my vision of old; my Lord has indeed made it to be true; and He was indeed kind to me when He brought me forth from the prison and brought you from the desert after the Shaitan had sown dissensions between me and my brothers, surely my Lord is benignant to whom He pleases; surely He is the Knowing, the Wise.

(12) It may be that your Lord will have mercy on you, and if you again return (to disobedience) We too will return (to punishment), and We have made hell a prison for the unbelievers.

(13) Said he: If you will take a god besides me, I will most certainly make you one of the imprisoned.

(14) O Prophet! surely We have made lawful to you your wives whom you have given their dowries, and those whom your right hand possesses out of those whom Allah has given to you as prisoners of war, and the daughters of your paternal uncles and the daughters of your paternal aunts, and the daughters of your maternal uncles and the daughters of your maternal aunts who fled with you; and a believing woman if she gave herself to the Prophet, if the Prophet desired to marry her-- specially for you, not for the (rest of) believers; We know what We have ordained for them concerning their wives and those whom their right hands possess in order that no blame may attach to you; and Allah is Forgiving, Merciful.

(15) So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are slain in the way of Allah, He will by no means allow their deeds to perish.
