And We have commanded man to be benevolent towards his parents. His mother bears him (in the womb) with pain and gives birth to him with pain. And bearing him (in the womb) and weaning of him (i.e. the period of pregnancy and feeding) is (spread over) thirty months. Till, when he attains to manhood and then reaches (the fully mature age of) forty years, he says: ‘O my Lord, bestow on me the ability to give You thanks for the favour which You have done to me and my parents, and that I may do such deeds as may please You, and endow me and my children with virtue and piousness. Assuredly I turn to You, and certainly I am of those who obey You in submissiveness.’
