Qur’an – Surah Al-Isra (17:23)

وَقَضَىٰ رَبُّكَ أَلَّا تَعْبُدُوا إِلَّا إِيَّاهُ وَبِالْوَالِدَيْنِ إِحْسَانًا ۚ إِمَّا يَبْلُغَنَّ عِندَكَ الْكِبَرَ أَحَدُهُمَا أَوْ كِلَاهُمَا فَلَا تَقُل لَّهُمَا أُفٍّ وَلَا تَنْهَرْهُمَا وَقُل لَّهُمَا قَوْلًا كَرِيمًا

Translation:

Your Lord has decreed that you worship none but Him, and that you show excellence in conduct to your parents. If one or both of them reach old age with you, do not say to them even “uff,” nor repel them, but speak to them a noble word.

Explanation:

The Qur’an prohibits even the slightest expression of annoyance toward parents. The word “uff” represents the smallest sign of irritation. This teaches that respect must be maintained at the highest level, even when we feel tired, frustrated, or disagree with them. True righteousness includes not only obedience, but also maintaining gentle speech and preserving their dignity at all times.
