What should be your behavior towards non Muslim parents?

Answer 1

You should treat them with respect, kindness, and modesty but not to follow their calling you, if any, to convert from Islam or to worship a partner with God, the one and only one God.

God says in Quran :

وَوَصَّيْنَا الْإِنسَانَ بِوَالِدَيْهِ حَمَلَتْهُ أُمُّهُ وَهْنًا عَلَىٰ وَهْنٍ وَفِصَالُهُ فِي عَامَيْنِ أَنِ اشْكُرْ لِي وَلِوَالِدَيْكَ إِلَيَّ الْمَصِيرُ ﴿١٤﴾ وَإِن جَاهَدَاكَ عَلَىٰ أَن تُشْرِكَ بِي مَا لَيْسَ لَكَ بِهِ عِلْمٌ فَلَا تُطِعْهُمَا ۖ وَصَاحِبْهُمَا فِي الدُّنْيَا مَعْرُوفًا ۖ وَاتَّبِعْ سَبِيلَ مَنْ أَنَابَ إِلَيَّ ۚ ثُمَّ إِلَيَّ مَرْجِعُكُمْ فَأُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ ﴿١٥﴾

(meaning English translation):

"And We(God-Allah) have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents, unto Me is the final destination. (14) But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do. (15)"

[Quran, chapter 31, verses 14-15]

Answer 2

In Islam, it is important to respect and honor one's parents regardless of their religion. Muslims are encouraged to treat their non-Muslim parents with kindness, compassion, and maintain strong family ties while upholding their own beliefs. It is also an opportunity to display the beauty of Islam through good character and conduct.
