225 [17:24] Thy Lord has commanded, “Worship none but Him, and show kindness to parents. If one of them or both of them attain old age with thee, never say unto them any word expressive of disgust nor reproach them, but address them with excellent speech. [17:25] “And lower to them the wing of humility out of tenderness. And say, ‘My Lord, have mercy on them even as they nourished me in my childhood. ’” [17:29] And if thou hast to turn away from them while seeking thy Lord’s mercy for which thou hopest, even then speak to them a gentle word. [49:12] O ye who believe! let not one people deride another people, who may be better than they, nor let women deride other women, who may be better than they. And defame not your own people, nor call one another by nicknames. Bad indeed is evil reputation after the profession of belief; and those who repent not are the wrongdoers.
