وَقَضىٰ رَبُّكَ أَلّا تَعبُدوا إِلّا إِيّاهُ وَبِالوالِدَينِ إِحسانًا ۚ إِمّا يَبلُغَنَّ عِندَكَ الكِبَرَ أَحَدُهُما أَو كِلاهُما فَلا تَقُل لَهُما أُفٍّ وَلا تَنهَرهُما وَقُل لَهُما قَولًا كَريمًا

Your Lord has decreed that you worship none but Him, and that you extend kindness to your parents. If one or both of them attain old age in your presence, don’t say ‘uff’ to them, nor scold them, but address them with respectful words.
