What is the legal right, according to Sharia, of the wife of a deceased brother who did not bequeath anything to her, and who had no children, in the estate of their deceased father, consisting of agricultural land, a farm tractor, a house, and an apartment?

To determine the right of the deceased brother's wife, you must first ascertain your brother's share of your father's inheritance.

1. Father's Inheritance: The father's inheritance is divided as follows: For the wife (your mother): One-eighth as a prescribed share due to the existence of a lineal descendant (as stated in the Almighty's words: "But if you have a child, then for them is one-eighth of what you leave"). The remainder: For the brothers and sisters by residuary right, with the male receiving the share of two females (as stated in the Almighty's words: "Allah instructs you concerning your children: for the male, what is equal to the share of two females").

2. Deceased Brother's Inheritance: Your brother's share of your father's inheritance is added to his private assets. Then, the brother's inheritance is divided as follows: For his wife: One-fourth as a prescribed share due to the absence of a lineal descendant (as stated in the Almighty's words: "But if you have no child, then for them is one-fourth of what you leave"). For his mother: One-sixth as a prescribed share due to the presence of multiple siblings (as stated in the Almighty's words: "But if he has brothers [or sisters], then for his mother is one-sixth"). The remainder: Divided among the brothers and sisters by residuary right, with the male receiving the share of two females.

It is recommended to refer inheritance matters to the Sharia courts for precise consideration and investigation.
