Is obedience to one's mother obligatory when she forbids attending Quran memorization circles and commands one to commit forbidden acts such as intermingling (free mixing) and listening to music, taking into consideration the Shariah principle: "There is no obedience to a created being in disobedience to the Creator"?

Obedience to parents is obligatory in matters that do not contradict the Sharia. Therefore, obedience to a mother is not obligatory in committing evil deeds; rather, it is forbidden, while still maintaining the duty of kindness towards her. You are not obligated to obey her in abandoning the pursuit of Islamic knowledge as long as you are able to combine it with secular studies. If seeking Islamic knowledge is an obligation upon you, then it is not permissible to obey her in abandoning it. If it is recommended, then her obedience is not obligatory if her command stems from foolishness and caprice.
