Al-Isra · Ayah 23
وَقَضَىٰ رَبُّكَ أَلَّا تَعْبُدُوٓا۟ إِلَّآ إِيَّاهُ وَبِٱلْوَٰلِدَيْنِ إِحْسَٰنًا إِمَّا يَبْلُغَنَّ عِندَكَ ٱلْكِبَرَ أَحَدُهُمَآ أَوْ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفٍّ وَلَا تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلًا كَرِيمًا
And your Lord has decreed that you worship not except Him, and to parents, good treatment. Whether one or both of them reach old age [while] with you, say not to them [so much as], "uff,"[735] and do not repel them but speak to them a noble word.
Translator's notes
[735] An expression of disapproval or irritation.
