Guarding oneself

In the name of Allah, the Most Gracious, the Most Merciful

(17:32) And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way.

(24:30) Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do.
(24:31) And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands’ fathers, their sons, their husbands’ sons, their brothers, their brothers’ sons, their sisters’ sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.

(24:60) And women of post-menstrual age who have no desire for marriage – there is no blame upon them for putting aside their outer garments [but] not displaying adornment. But to modestly refrain [from that] is better for them. And Allah is Hearing and Knowing.

(70:19) Indeed, mankind was created anxious:
(70:20) When evil touches him, impatient,
(70:21) And when good touches him, withholding [of it],
(70:22) Except the observers of prayer –
(70:23) Those who are constant in their prayer
(70:24) And those within whose wealth is a known right
(70:25) For the petitioner and the deprived –
(70:26) And those who believe in the Day of Recompense
(70:27) And those who are fearful of the punishment of their Lord –
(70:28) Indeed, the punishment of their Lord is not that from which one is safe –
(70:29)And those who guard their private parts
(70:30)Except from their wives or those their right hands possess, for indeed, they are not to be blamed –
(70:31)But whoever seeks beyond that, then they are the transgressors –
(70:32)And those who are to their trusts and promises attentive
(70:33)And those who are in their testimonies upright
(70:34)And those who [carefully] maintain their prayer:
(70:35)They will be in gardens, honored.
