The word(s) "chaste" appears 11 time(s) in 10 verse(s) in Quran in Mohsin Khan translation.

(1) And whoever of you have not the means wherewith to wed free, believing women, they may wed believing girls from among those (slaves) whom your right hands possess, and Allah has full knowledge about your Faith; you are one from another. Wed them with the permission of their own folk (guardians, Auliya' or masters) and give them their Mahr according to what is reasonable; they (the above said captive and slave-girls) should be chaste, not committing illegal sex, nor taking boy-friends. And after they have been taken in wedlock, if they commit illegal sexual intercourse, their punishment is half that for free (unmarried) women. This is for him among you who is afraid of being harmed in his religion or in his body; but it is better for you that you practise self-restraint, and Allah is Oft-Forgiving, Most Merciful.

(2) Made lawful to you this day are At-Tayyibat [all kinds of Halal (lawful) foods, which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of the people of the Scripture (Jews and Christians) is lawful to you and yours is lawful to them. (Lawful to you in marriage) are chaste women from the believers and chaste women from those who were given the Scripture (Jews and Christians) before your time when you have given their due Mahr (bridal-money given by the husband to his wife at the time of marriage), desiring chastity (i.e. taking them in legal wedlock) not committing illegal sexual intercourse, nor taking them as girl-friends. And whosoever disbelieves in Faith [i.e. in the Oneness of Allah and in all the other Articles of Faith i.e. His (Allah's) Angels, His Holy Books, His Messengers, the Day of Resurrection and Al-Qadar (Divine Preordainments)], then fruitless is his work; and in the Hereafter he will be among the losers.

(3) She said: "How can I have a son, when no man has touched me, nor am I unchaste?"

(4) "O sister (i.e. the like) of Harun (Aaron) ! Your father was not a man who used to commit adultery, nor your mother was an unchaste woman."

(5) And those who accuse chaste women, and produce not four witnesses, flog them with eighty stripes, and reject their testimony forever. They indeed are the Fasiqun (liars, rebellious, disobedient to Allah).

(6) Verily, those who accuse chaste women, who never even think of anything touching their chastity and are good believers - are cursed in this life and in the Hereafter, and for them will be a great torment -

(7) And let those who find not the financial means for marriage keep themselves chaste, until Allah enriches them of His Bounty. And such of your slaves as seek a writing (of emancipation), give them such writing, if you find that there is good and honesty in them. And give them something (yourselves) out of the wealth of Allah which He has bestowed upon you. And force not your maids to prostitution, if they desire chastity, in order that you may make a gain in the (perishable) goods of this worldly life. But if anyone compels them (to prostitution), then after such compulsion, Allah is Oft-Forgiving, Most Merciful (to those women, i.e. He will forgive them because they have been forced to do this evil act unwillingly).

(8) And beside them will be Qasirat-at-Tarf [chaste females (wives), restraining their glances (desiring none except their husbands)], with wide and beautiful eyes.

(9) And beside them will be Qasirat-at-Tarf [chaste females (wives) restraining their glances (desiring none except their husbands)], (and) of equal ages.

(10) Wherein both will be Qasirat-ut-Tarf [chaste females (wives) restraining their glances, desiring none except their husbands], with whom no man or jinni has had tamth before them.
