Q 4:
Does the deceased's wife inherit from her father-in-law?
A:
The wife of the deceased does not inherit from her father-in-law if her husband dies before his father as we mentioned in the answer of the second question. However, if the husband inherits from his father after his death, the wife will inherit from her husband after his death of the property which he inherited from his father. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
