Is not naming a son after his father before the latter's death, then naming him that name two years after the death, considered an act of disobedience to the father?

The rights of parents are immense, coming directly after the rights of Allah. Obedience to them is obligatory in what is good and permissible. Therefore, rejecting a father's request regarding naming a child is a mistake for which one must seek forgiveness. The father's will should be fulfilled after his death, and one should frequently supplicate for him, give charity on his behalf, and maintain ties with his relatives and friends, to compensate for any shortcomings in dutifulness towards him during his lifetime.
