Does the hymen indicate a girl's chastity in Sharia, and is a husband permitted to divorce his wife if he finds her not to be a virgin?

The presence of the hymen in a righteous woman is an indication of her chastity, and its absence in a woman of bad character indicates a lack of chastity. However, the hymen is not considered conclusive proof of chastity or lack thereof. It may be lost by a chaste woman due to an accident, and it may remain intact in a wicked woman despite her committing forbidden acts.
