We have charged man, that he be kind to his parents; his mother bore him painfully, and painfully she gave birth to him; his bearing and his weaning are thirty months. Until, when he is fully grown, and reaches forty years, he says, 'O my Lord, dispose me that I may be thankful for Thy blessing wherewith Thou hast blessed me and my father and mother, and that I may do righteousness well-pleasing to Thee; and make me righteous also in my seed. Behold, I repent to Thee, and am among those that surrender.'
