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 Behold, Luqman said to his son by way of instruction: "O my son! join not in worship (others) with Allah: for false worship is indeed the highest wrong-doing." 13 And We have enjoined man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming. 14 But if they strive with thee to make thee associate with Me that whereof thou hast no knowledge, then do not obey them. Keep them company honourable in this world; but follow the way of him who turns to Me. Then unto Me you shall return, and I shall tell you what you were doing.') 15 "O my dear son," [continued Luqman,] "verily, if there be but the weight of a mustard-seed, and though it be [hidden] in a rock, or in the skies, or in the earth, God will bring it to light: for, behold, God is unfathomable [in His wisdom,] all-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 "And swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster. 18 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
