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 have enjoined man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming. 14 If they try to force you to associate with Me that of which you have no knowledge, do not obey them. Live with them honourably in the world, but follow the way of him who turns to Me. Your returning is to Me in the end, when I will tell you what you did. 15 (Lokman said:) 'My son, if it should be but the weight of one grain of mustardseed, and though it be on a rock, or in the heavens, or in the earth, Allah shall bring it. Surely, Allah is the Subtle, Aware. 16 O my son, perform the prayer, and bid unto honour, and forbid dishonour. And bear patiently whatever may befall thee; surely that is true constancy. 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 Be moderate in your stride and lower your voice. Verily the most disgusting of all voices is the braying of the donkey.” 19
