What is the ruling of Islamic law concerning dealing with a man accused of sexually harassing and raping his daughter, without physical evidence, but with circumstantial evidence? And what is the ruling concerning his wife abandoning him, seeking divorce from him, and expelling him from the home while he is ill?

Rape is not established merely by allegation or circumstantial evidence; rather, it requires the presence of four witnesses. However, the claim of harassment by the father is referred to the judiciary for consideration, and if his moral corruption is proven, the girl must be removed from him.

As for the ruling on expelling a corrupt father from the house, it is not permissible to expel him if the house is his property or if he is poor and in need. They must house him elsewhere and care for him, because a parent's corruption does not negate the duty of righteousness towards him, and they must advise him kindly. However, if the house belongs to his wife and his corruption is proven, she may seek a judicial divorce.
