Ayah: 23

۞ وَقَضَىٰ رَبُّكَ أَلَّا تَعۡبُدُوٓاْ إِلَّآ إِيَّاهُ وَبِٱلۡوَٰلِدَيۡنِ إِحۡسَٰنًاۚ إِمَّا يَبۡلُغَنَّ عِندَكَ ٱلۡكِبَرَ أَحَدُهُمَآ أَوۡ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفّٖ وَلَا تَنۡهَرۡهُمَا وَقُل لَّهُمَا قَوۡلٗا كَرِيمٗا

23. For your Lord "Allāh' has decreed, that you worship none but Him, and that you must honor and do good to your parents13. If either or both of them reach old age in your care, never say to them even 'ugh'14 and never rebuke them, rather speak to them noble words.

13. Love for a hurtful parent: Forgive their transgressions. Show mercy. Share the Qur’an with them. Be kind to them. Choose to speak nicely of them. Teach your children to honor and be kind to their grandparents.
14. One is not to show any kind of disapproval in their service to their parents even as small a word as "uff" or "ugh", let alone what is beyond that.
