We have prescribed for man kindness towards his parents. His mother bore him with trouble and brought him forth with trouble; and the bearing of him and the weaning of him is thirty months; until, when he reaches puberty, and reaches forty years, he says, 'Lord! stir me up that I may be thankful for thy favours wherewith thou hast favoured me and my parents; and that I may do right to please Thee; and make it right for me in my offspring; verily, I turn repentant unto Thee, and, verily, I am of those resigned.'
