Is it obligatory to obey a father in severing ties of kinship with my paternal uncles, and what is the ruling on a father's will not to mention the names of his siblings upon his death?

Strife between a father and his brothers is a gateway for Satan, leading to hatred. It is necessary to reconcile differences, as Allah Almighty says: "No good is there in much of their private conversation, except for whoever enjoins charity or that which is right or reconciliation between people." Obedience to a father is in what is good, not in disobedience. Severing ties of kinship is a sin, and paternal uncles are among the kin whose ties must be maintained. The father's will not to announce his death is a permissible matter that is not obligatory to fulfill.
