Surah Al-Ankabut (The Spider), Verse 8

وَوَصَّیْنَا الْاِنْسَانَ بِوَالِدَیْهِ حُسْنًا وَاِنْ جٰهَدٰكَ لِتُشْرِكَ بِیْ مَا لَیْسَ لَكَ بِهٖ عِلْمٌ فَلَا تُطِعْهُمَا اِلَیَّ مَرْجِعُكُمْ فَاُنَبِّئُكُمْ بِمَا كُنْتُمْ تَعْمَلُوْنَ ۟

Wa wassainal insaana biwaalidaihi husnanw wa in jaahadaaka litushrika bee maa laisa laka bihee 'ilmun falaa tuti'humaa; ilaiya marji'ukum fa unabbi'ukum bimaa kuntum ta'maloon

“We have enjoined on man kindness to parents: but if they (either of them) strive (to force) thee to join with Me (in worship) anything of which thou hast no knowledge, obey them not. Ye have (all) to return to me, and I will tell you (the truth) of all that ye did.”
