Allah, your Creator, has ordained, that you worship no one but Him and you adore Him with appropriate acts and rites and that you commit your parents to your kind care. When one or both of them attain old age they expect your friendly disposition by your conduct to them. Therefore do not offend them by giving vent to an exclamation of impatience or disgust nor should you rebuke or reprimand them and let your dissertation with them be a sweet discourse.
