Is it permissible for a father to marry his son’s divorced or widowed wife (whether consummated or not), or for a son to marry his father’s divorced or widowed wife (whether consummated or not)?
It is not permissible for either the father or the son to marry the other's wife, whether or not the marriage was consummated.
A father-in-law and daughter-in-law can never be married to each other. This is among the eternally prohibited relationships (maḥarramāt abadiyyah).
