there is a difference of opinion among the scholars. Some scholars hold that she inherits from him as a mother, while the remainder—if he has no agnatic heir—goes to her agnatic heirs; whoever among them is most closely related to her through the male line receives it. Note our qualification: if he has no agnatic heir. Can this child, whose lineage has been disavowed on his father’s side, have an agnatic heir? Yes, this is possible if he has children, for they are his agnatic heirs.
The correct view is that the mother inherits from him as both a mother and a residuary heir, based on the hadith: “A woman takes possession of three inheritances: that of her freed slave, her foundling, and her child concerning whom she entered into li'an” (1). Although this hadith is weak, its meaning is supported by analogy: her agnatic heirs are connected to him only through her, so how can the one connected through another be stronger than the one through whom he is connected?
Accordingly, if this disavowed child dies and has no agnatic heir, we say that his mother receives one-third as her prescribed share and the remainder as a residuary heir. According to the second view—the position of the school—she inherits only the inheritance of a mother: she receives one-third as her prescribed share, and the remainder goes to the nearest male agnatic heir among her agnatic relatives. Thus, if she has a father and brothers, the inheritance goes to the father. If she has a grandfather and brothers, the correct view is that the inheritance goes to the grandfather. According to those who allow the brothers to inherit alongside the grandfather, it is apportioned according to their view. But the correct view is that the grandfather takes the place of the father and completely excludes the brothers from inheritance.
