What is the ruling on Islamic celebrations if the parents do not approve, and is it permissible to disobey them or is it obligatory to obey them and compromise?

The Islamic celebration of marriage is a ceremony regulated by Sharia law, free from forbidden acts such as intermingling (between sexes), ostentatious display (of beauty by women), and prohibited music. It is permissible to introduce joy and happiness with the duff (hand drum) and purposeful singing among women. Marriage celebrations in Islam combine joy and happiness with chastity, modesty, and avoidance of forbidden things. The women's celebration is separate from the men's, and the men are in their own designated area. It is sunnah to prepare a feast without extravagance. The purpose of this is to publicize the marriage and distinguish it from illicit relations, and to bring joy to the spouses and their families.

If the parents refuse to abide by the rulings of Sharia and insist on introducing forbidden acts, then you must advise them and explain the ruling of Sharia. If they respond, then all praise is due to Allah. But if they insist, then withdraw from the place where the forbidden act is taking place and declare your dislike for it, based on the Almighty's saying: (وَقَدْ نَزَّلَ عَلَيْكُمْ فِي الْكِتَابِ أَنْ إِذَا سَمِعْتُمْ آيَاتِ اللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلا تَقْعُدُوا مَعَهُمْ حَتَّى يَخُوضُوا فِي حَدِيثٍ غَيْرِهِ إِنَّكُمْ إِذًا مِثْلُهُمْ) "And He has already sent down to you in the Book that when you hear the verses of Allah being disbelieved in and ridiculed, then do not sit with them until they enter into another conversation. Indeed, you would then be like them."
