The Light - 24:31
And tell the believing women that they should guard their eyes and guard their chastity and not show their fair parts except those which should be uncovered. Let them cover their veils over their breasts. And let them not show the fair parts of their bodies to anyone except their husbands, their fathers, their husbands´ fathers, their husbands´ fathers, their sons, their husbands´ sons, their brothers, their brothers´ sons, their sisters´ sons, other women, male servants and laborers who do not have sexual power, and children who do not yet understand the sexual aspects of women. And let them not stamp their feet to show off their hidden parts. O you who believe, turn to Allah collectively so that you may be successful.
To turn to Allah; to repent and ask for forgiveness:
The Table Spread/5:39
Whoever repents and reforms after this injustice, Allah will accept his return. Surely Allah is Forgiving, Merciful.
The Table Spread/5:74
Will they not turn to Allah and ask forgiveness from Him? Allah is Forgiving, Merciful.
The Repentance/9:117
Allah has accepted the repentance of the Messenger and those who emigrated and those who helped. They followed him at a time of difficulty when some of them almost lost heart. Then He accepted their turning (repentance). He is Most Compassionate towards them, Most Merciful.
The Prohibition/66:4
If you both repent to Allah, your hearts will be turned. And if you support one another against him (the Messenger), Allah is his guardian, and Jibril and the righteous believers and the angels support him.
