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 (remember) when Luqman said to his son when he was advising him: "O my son! Join not in worship others with Allah. Verily! Joining others in worship with Allah is a great Zulm (wrong) indeed. 13 We have enjoined man to show kindness to his parents -- for his mother bears him, in hardship upon hardship, and his weaning takes two years. [We said] Give thanks to Me and to your parents; all will return to Me. 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 "My son, God keeps the records of all the good and evil deeds, even if they are as small as a grain of mustard seed, hidden in a rock or in the heavens or the earth. God is subtle and All-aware. 16 "O my son! establish regular prayer, enjoin what is just, and forbid what is wrong: and bear with patient constancy whatever betide thee; for this is firmness (of purpose) in (the conduct of) affairs. 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 And be modest in thy gait and lower thy voice; verily the most abominable of voices is the voice of the ass. 19
