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 (Remember) when Luqman counselled his son: "O son, do not associate any one with God. To associate others with God is a grievous wrong." 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 But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with appropriate kindness and follow the way of those who turn back to Me [in repentance]. Then to Me will be your return, and I will inform you about what you used to do. 15 "O my son, whatsoever it may be, even though equal to a mustard seed in weight, or within a rock or in the sky or in the earth, God will bring it forth. Verily God is perceptive, all-aware. 16 “O my son! Keep the prayer established, and enjoin goodness and forbid from evil, and be patient upon the calamity that befalls you; indeed these are acts of great courage.” 17 “And do not contort your cheek while talking to anyone, nor boastfully walk upon the earth; indeed Allah does not like any boastful, haughty person.” 18 Walk modestly, and lower your voice; the most hideous of voices is the braying of the donkey. 19
