Shaykh al-Islām—may Allah have mercy on him—was asked:

A man died leaving a daughter, the young children of a paternal half-brother, a grown male paternal cousin, a female paternal cousin, and a maternal half-brother who is not also one of his paternal cousins. Who inherits the estate, and who becomes the daughter’s guardian?

He replied:

As for the inheritance, half goes to the daughter and half to the brother’s sons. As for the girl’s custody, it belongs to the female paternal cousin, rather than to her father’s maternal half-brother or to the male paternal cousin, who is not a mahram (a relative permanently forbidden to her in marriage). He has guardianship over the orphan girl’s property; that guardianship belongs to an executor or his deputies.

He was asked:

What is the ruling concerning someone who leaves two daughters and a paternal uncle who is his father’s maternal half-brother?

He replied:

If the deceased leaves his two daughters and his maternal half-brother, his maternal half-brother receives nothing, by agreement of the imams. Rather, the two daughters receive two-thirds, and the remainder goes to the residuary heirs, if he has any. Otherwise, it reverts to the two daughters or goes to the public treasury.
