Al Isra, 23 Ayah
17:23
۞ 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 ٢٣
Wa Qađá Rabbuka 'Allā Ta`budū 'Illā 'Īyāhu Wa Bil-Wālidayni 'Iĥsānāan ۚ 'Immā Yablughanna `Indaka Al-Kibara 'Aĥaduhumā 'Aw Kilāhumā Falā Taqul Lahumā 'Uffin Wa Lā Tanharhumā Wa Qul Lahumā Qawlāan Karīmāan
And your Lord has decreed that you not worship 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," and do not repel them but speak to them a noble word.
