Now, We have enjoined upon man goodness toward his parents. In pain did his mother bear him, and in pain did she give him birth. The carrying of the child and his total dependence on her took thirty months. And so, when he attains maturity and reaches forty years, he says, "My Lord! Enable me to be grateful for the blessings You have given me and to my parents, and that I may do works that meet Your Approval. And cause my generations to be righteous as well. Verily, unto You I turn, and truly do I submit to You." (2:233), (7:189), (31:14).
