Obedience to parents is obligatory as long as it does not go beyond a child’s ability or inflicts a harm to him. This is based on the Prophet’s saying, “There is no harm to be inflicted or reciprocated”.

Divorcing a wife without a justifiable or a legal reason is prohibited, since it involves injustice to wife, husband and their children.

Therefore, you are not supposed to obey your parents in divorcing your wife. You have to speak to your parents in a gentle way. You must not dissever your relations with them.

Almighty Allah knows best.
