Say: Obey Allah and obey the Messenger; but if you turn back, then on him rests that which is imposed on him and on you rests that which is imposed on you; and if you obey him, you are on the right way; and nothing rests on the Messenger but clear delivering (of the message).

And We have enjoined on man doing of good to his parents; with trouble did his mother bear him and with trouble did she bring him forth; and the bearing of him and the weaning of him was thirty months; until when he attains his maturity and reaches forty years, he says: My Lord! grant me that I may give thanks for Thy favor which Thou hast bestowed on me and on my parents, and that I may do good which pleases Thee and do good to me in respect of my offspring; surely I turn to Thee, and surely I am of those who submit.
