We have enjoined man to be kind to his parents. His mother has carried him in travail, and bore him in travail, and his gestation and weaning take thirty months. When he comes of age and reaches forty years, he says, ‘My Lord! Inspire me to give thanks for Your blessing with which You have blessed me and my parents, and that I may do righteous deeds which may please You, and invest my descendants with righteousness. Indeed I have turned to you in penitence, and I am one of the muslims.’
