Is it permissible for a man to take back his wife after divorcing her for the third time, as a result of discord and talk caused by others?

If a man divorces his wife with three pronouncements, she becomes irrevocably separated from him and unlawful for him until she marries another husband. Then, if that husband divorces her, it becomes permissible for the questioner's father to marry her with a new contract.

Striving to cause discord between spouses is among the gravest of reprehensible acts, and it is the work of Satan and his soldiers.
