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 Luqman said to his son, counselling him, "My son, do not associate anything with God. Associating others with Him is a terrible wrong." 13 And We have enjoined on man (to be good) to his parents: in travail upon travail did his mother bear him, and in years twain was his weaning: (hear the command), "Show gratitude to Me and to thy parents: to Me is (thy final) Goal. 14 But if they strive with you to make you associate with Me that of which you have no knowledge, do not obey them. And accompany them in this life with kindness; and follow the Path of he who turned to Me. To Me you shall return and I will inform you of all that you have done. 15 [Luqman further said,] "O my son! Though it be but the weight of a grain of mustard seed and though it be hidden in a rock, or in the heavens or on the earth, God will bring it forth. Truly, God is the knower of all subtleties and He is aware. 16 O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination. 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 modest in thy walk, and lower thy voice; the most hideous of voices is the ass's.' 19
