We gave wisdom to Lokman (saying): 'Give thanks to Allah. He who gives thanks, thanks only for himself, but whosoever is ungrateful, surely, Allah is the Rich, the Praised' 12 And (remember) when Luqman said to his son when he was advising him: "O my son! Join not in worship others with Allah. Verily! Joining others in worship with Allah is a great Zulm (wrong) indeed. 13 We have committed man about his parents. His mother carries him in her womb in weakness and debility, weaning him in two years. So he should be grateful to Me and his parents. To Me is the journeying back. 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 dear son," [continued Luqman,] "verily, if there be but the weight of a mustard-seed, and though it be [hidden] in a rock, or in the skies, or in the earth, God will bring it to light: for, behold, God is unfathomable [in His wisdom,] 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 swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster. 18 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
