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 partners - His mother beareth him in weakness upon weakness, and his weaning is in two years - Give thanks unto Me and unto thy parents. Unto Me is the journeying. 14 But if they strive with thee to make thee associate with Me that whereof thou hast no knowledge, then do not obey them. Keep them company honourable in this world; but follow the way of him who turns to Me. Then unto Me you shall return, and I shall tell you what you were doing.') 15 O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware; 16 "O my dear son! Be constant in prayer, and enjoin the doing of what is right and forbid the doing of what is wrong, and bear in patience whatever [ill] may befall thee: this, behold, is something to set one's heart upon! 17 And do not turn your face away from people in contempt, nor go about in the land exulting overmuch; surely Allah does not love any self-conceited boaster; 18 And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys." 19
