Quran 29:8 from Surah Al-Ankaboot on Divine Marvels.
وَوَصَّيۡنَا ٱلۡإِنسَٰنَ بِوَٰلِدَيۡهِ حُسۡنٗاۖ وَإِن جَٰهَدَاكَ لِتُشۡرِكَ بِي مَا لَيۡسَ لَكَ بِهِۦ عِلۡمٞ فَلَا تُطِعۡهُمَآۚ إِلَيَّ مَرۡجِعُكُمۡ فَأُنَبِّئُكُم بِمَا كُنتُمۡ تَعۡمَلُونَ
English translation: And We have enjoined (on) man goodness to his parents goodness to his parents but if they both strive against you to make you associate with Me what not you have of it any knowledge then (do) not obey both of them To Me (is) your return and I will inform you about what you used (to) do
Transliteration: wawassayna al-insana biwalidayhi hus'nan wa-in jahadaka litush'rika bi ma laysa laka bihi il'mun fala tuti'huma ilayya marji'ukum fa-unabbi-ukum bima kuntum ta'maluna
