What is the ruling on obeying parents if they prevent their son from performing supererogatory acts (sunan and nawafil) and reciting the Qur’an?

Filial piety is obligatory, and disobeying one's parents is forbidden. However, there is a difference between obligatory and recommended acts of obedience. Obedience to parents is not obligatory if they command one to abandon an obligation, such as congregational prayer, because "there is no obedience to a creature in disobedience to the Creator." As for recommended acts and supererogatory prayers, obedience to them is obligatory if their command is concerning something permissible and there is a benefit for them in it, or a legitimate justification, or if there is hardship for the child. However, if their command is to completely abandon supererogatory acts without any benefit for them, or if it stems from foolishness or lack of religiosity, then obedience to them is not obligatory. Instead, one must deal with them kindly and treat them with goodness.
