[16:78] GOD brought you out of your mothers' bellies knowing nothing, and He gave you the hearing, the eyesight, and the brains, that you may be appreciative.
[31:14] We enjoined the human being to honor his parents. His mother bore him, and the load got heavier and heavier. It takes two years (of intensive care) until weaning. You shall be appreciative of Me, and of your parents. To Me is the ultimate destiny.
 Your Lord has decreed that you shall not worship except Him, and your parents shall be honored. As long as one or both of them live, you shall never say to them, "Uff" (the slightest gesture of annoyance), nor shall you shout at them; you shall treat them amicably.
[46:15] We enjoined the human being to honor his parents. His mother bore him arduously, gave birth to him arduously, and took intimate care of him for thirty months. When he reaches maturity, and reaches the age of forty, he should say, "My Lord, direct me to appreciate the blessings You have bestowed upon me and upon my parents, and to do the righteous works that please You. Let my children be righteous as well. I have repented to You; I am a submitter."
