Who takes precedence in righteousness: the father's relatives or the mother's relatives, when rights conflict?

Maintaining kinship ties is one of the best deeds. The rights within these ties vary according to the degree of kinship. The mother is given precedence over the father in righteousness, then children, then grandparents, then siblings, then all other unmarriageable relatives (mahārim), with the closest being prioritized. When the degree of kinship is equal, the mother's relatives are preferred because the mother is given precedence over the father in righteousness, and because the maternal aunt (khālah) is in the status of a mother.
