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 [mention, O Muhammad], when Luqman said to his son while he was instructing him, "O my son, do not associate [anything] with Allah. Indeed, association [with him] is great injustice." 13 "And [God says:] 'We have enjoined upon man goodness towards his parents: his mother bore him by bearing strain upon strain, and his utter dependence on her lasted two years: [hence, O man,] be grateful towards Me and towards thy parents, [and remember that] with Me is all journeys' end. 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 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 (contemptuously) turn your face away from people, nor tread haughtily upon earth. Allah does not love the arrogant and the vainglorious. 18 "Hence, be modest in thy bearing, and lower thy voice: for, behold, the ugliest of all voices is the [loud] voice of asses…" 19
