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 (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 And We charged the human concerning his parents, for his mother bore him in weakness upon weakness, and his weaning was in two years. Be thankful to Me and to your parents, to Me is the arrival. 14 But if they strive with thee to make thee ascribe unto Me as partner that of which thou hast no knowledge, then obey them not. Consort with them in the world kindly, and follow the path of him who repenteth unto Me. Then unto Me will be your return, and I shall tell you what ye used to do - 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 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 swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster. 18 Be modest in thy bearing and subdue thy voice. Lo! the harshest of all voices is the voice of the ass. 19
