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, in warning: 'My son, associate none with Allah, to associate others with Allah is a tremendous 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 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 O my dear son! Lo! 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 will bring it forth. Lo! Allah is Subtile, Aware. 16 Son, establish Prayer, enjoin all that is good and forbid all that is evil, and endure with patience whatever affliction befalls you. Surely these have been emphatically enjoined. 17 "And turn not thy cheek away from people in [false] pride, and walk not haughtily on earth: for, behold, God does not love anyone who, out of self-conceit, acts in a boastful manner. 18 And pursue the right course in your going about and lower your voice; surely the most hateful of voices is braying of the asses. 19
