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 recall what time Luqman said unto his son, while he was exhorting him: O my son! associate not aught with Allah; verily this associating is surely 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 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, whatsoever it may be, even though equal to a mustard seed in weight, or within a rock or in the sky or in the earth, God will bring it forth. Verily God is perceptive, all-aware. 16 O my son, fulfil your moral obligations, bid what is known to be right and forbid what is wrong, and bear with patience what befalls you. These are indeed acts of courage and resolve. 17 “And do not contort your cheek while talking to anyone, nor boastfully walk upon the earth; indeed Allah does not like any boastful, haughty person.” 18 And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys." 19
