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 upon man concerning his parents - his mother beareth him in hardship upon hardship and his weaning is in two years: give thanks unto Me and unto thy parents; unto Me is the goal. 14 "But if they strive to make thee join in worship with Me things of which thou hast no knowledge, obey them not; yet bear them company in this life with justice (and consideration), and follow the way of those who turn to me (in love): in the end the return of you all is to Me, and I will tell you the truth (and meaning) of all that ye 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 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 Do not avert your face from people out of haughtiness and do not walk with pride on the earth: for, behold, God does not love arrogant and boastful people. 18 Be modest in thy bearing and subdue thy voice. Lo! the harshest of all voices is the voice of the ass. 19
