Is it obligatory to honor and obey one's father and give him money, even if he abandoned his family in difficult circumstances and focused on his other family, knowing that relatives are more deserving of money?

The father's neglect of financial support and care is a sin, as he is legally responsible for his children. His disagreements with their mother do not justify such neglect. It is obligatory to honor and be good to one's father, even if he mistreats one, because his mistreatment does not negate the obligation of honoring him. If the father has no money, his financial support becomes obligatory upon his capable children. The father's financial support takes precedence over the mother's in cases of conflict, according to some scholars.
