Chastity is mentioned in the Quran in these verses:

[5:5] Today, all good food is made lawful for you. The food of the people of the scripture is lawful for you. Also, you may marry the chaste women among the believers, as well as the chaste women among the followers of previous scripture, provided you pay them their due dowries. You shall maintain chastity, not committing adultery, nor taking secret lovers. Anyone who rejects faith, all his work will be in vain, and in the Hereafter he will be with the losers.

[23:1] Successful indeed are the believers;

[23:2] who are reverent during their Contact Prayers (Salat).

[23:3] And they avoid vain talk.

[23:4] And they give their obligatory charity (Zakat).

[23:5] And they maintain their chastity.

[23:6] Only with their spouses, or those who are rightfully theirs, do they have sexual relations; they are not to be blamed.

[24:30] Tell the believing men that they shall subdue their eyes (and not stare at the women), and to maintain their chastity. This is purer for them. God is fully Cognizant of everything they do.

[24:31] And tell the believing women to subdue their eyes, and maintain their chastity. They shall not reveal any parts of their bodies, except that which is necessary. They shall cover their chests, and shall not relax this code in the presence of other than their husbands, their fathers, the fathers of their husbands, their sons, the sons of their husbands, their brothers, the sons of their brothers, the sons of their sisters, other women, the male servants or employees whose sexual drive has been nullified, or the children who have not reached puberty. They shall not strike their feet when they walk in order to shake and reveal certain details of their bodies. All of you shall repent to God, O you believers, that you may succeed.

[66:12] Also Mary, the Amramite. She maintained her chastity, then we blew into her from our spirit. She believed in the words of her Lord and His scriptures; she was obedient.

[70:26] They believe in the Day of Judgment.

[70:27] They reverence their Lord’s requital.

[70:28] Their Lord’s requital is not taken for granted.

[70:29] They keep their chastity.

[70:30] (They have relations) only with their spouses, or what is legally theirs –

[70:31] anyone who transgresses these limits is a sinner.
