Heaven can only be achieved with piety, only women who will enter shalihah paradise, one woman is proved by some character and morals, one of them and most important is to maintain self-respect. Allah Subhanahu waTa'ala says, that is,
"The righteous woman is the obedient to God again to take care of her when her husband is not there because Allah has nourished them" (Surat an-Nisa`: 34).
This verse stipulates that keeping oneself a form of the obedience of a shalihah woman to God and then to her husband.
