If a son, born free through a freedwoman mother, frees his father (the original slave), does the Wala' of the father's other descendants transfer to the son?
General Chapter
Al-Mughni
Book of Walā' (Patronage)
Primary text
If a son, whose mother was a freedwoman, purchases his father (the slave) and frees him, the Wala' transfers to the purchasing son. This grants him the Wala' of his father, and consequently, the Wala' of all his father's descendants (his siblings and their progeny) is drawn to him. The Wala' of the purchasing son, however, remains dedicated to the patron of his mother.

If this son (born to the slave and freedwoman) marries another freedwoman and has children, and his grandfather (the original slave's patron) is purchased, the grandfather becomes free under the grandson. The grandson inherits the Wala' of his father and all his paternal uncles and aunts (the grandfather's other freed children), along with the Wala' of all those whom they freed. However, the purchaser's Wala' remains tied to the patron of his paternal grandmother (the original freedwoman mother).
