In the scenario mentioned by you, the parents need to be whipped. How can they kick their prostitute daughter out when they had trained and qualified her to be a candidate for Jahannam by opening the gates of immorality and prostitution for her?

The major sins she commits will be loaded onto the parents. On the Day of Qiyaamah they will understand the villainy of their satanism. They had taught her the satanism of immorality and prostitution, now they want to lament and shed tears. It is too late.

Her apostasy (Irtidaad) will be loaded on to her parents. They must now suffer the consequences of their own shaitaaniyat. If they are Muslims, then obviously they will not be able to harbour the murtaddah. They have to expel her from their home.
