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 when Lokman said to his son, admonishing him, 'O my son, do not associate others with God; to associate others with God is a mighty wrong. 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 press you to associate others with Me in My Divinity, (to associate) those regarding whom you have no knowledge (that they are My associates), do not obey them. And yet treat them well in this world, and follow the way of him who turns to Me in devotion. Eventually it is to Me that all of you shall return, and I shall then tell you all that you did.” 15 O my son! though it be but the weight of a grain of mustard-seed, and though it be in a rock or in the heavens, or in the earth, Allah shall bring it forth. Verily Allah is subtile, 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 do not turn your cheek [in contempt] toward people and do not walk through the earth exultantly. Indeed, Allah does not like everyone self-deluded and boastful. 18 Walk modestly and lower your voice, for the ugliest of all voices is the braying of the ass." 19
