and, indeed, we granted this wisdom unto Luqman: "Be grateful unto God - for he who is grateful [unto Him] is but grateful for the good of his own self; whereas he who chooses to be ungrateful [ought to know that,] verily, God is self-sufficient, ever to be praised!" 12 And [mention, O Muhammad], when Luqman said to his son while he was instructing him, "O my son, do not associate [anything] with Allah. Indeed, association [with him] is great injustice." 13 We have committed man about his parents. His mother carries him in her womb in weakness and debility, weaning him in two years. So he should be grateful to Me and his parents. To Me is the journeying back. 14 And if the twain strive with thee to make thee associate with Me that for which thou hast no knowledge, then obey them not. And bear them thou company in the world reputably, and follow thou the path of him who turneth penitently unto Me. Then unto Me is your return, and I shall declare unto you that which ye have been working. 15 O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware; 16 "O my dear son! Be constant in prayer, and enjoin the doing of what is right and forbid the doing of what is wrong, and bear in patience whatever [ill] may befall thee: this, behold, is something to set one's heart upon! 17 Do not hold men in contempt, and do not walk with hauteur on the earth. Verily God does not like the proud and boastful. 18 Be moderate in your stride and lower your voice. Verily the most disgusting of all voices is the braying of the donkey.” 19
