Sahih International:
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," and do not repel them but speak to them a noble word. (Al-Isra [17] : 23)

Your Lord has decreed that you worship none but Him, and do good to parents. If any one of them or both of them reach old age, do not say to them: uff (a word or expression of anger or contempt) and do not scold them, and address them with respectful words,
