Al Isra’ Ayah 23

۞ وَقَضَىٰ رَبُّكَ أَلَّا تَعْبُدُوٓاْ إِلَّآ إِيَّاهُ وَبِٱلْوَٲلِدَيْنِ إِحْسَـٰنًا‌ۚ إِمَّا يَبْلُغَنَّ عِندَكَ ٱلْكِبَرَ أَحَدُهُمَآ أَوْ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفٍّ وَلَا تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلاً كَرِيمًا ٢٣ For your Lord has decreed that you worship none but Him. And honour your parents. If one or both of them reach old age in your care, never say to them ?even? ‘ugh,’ nor yell at them. Rather, address them respectfully.
