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 charged man concerning his parents -- his mother bore him in weakness upon weakness, and his weaning was in two years -- 'Be thankful to Me, and to thy parents; to Me is the homecoming. 14 But if they strive with you to make you associate with Me that of which you have no knowledge, do not obey them. And accompany them in this life with kindness; and follow the Path of he who turned to Me. To Me you shall return and I will inform you of all that you have done. 15 [Luqman further said,] "O my son! Though it be but the weight of a grain of mustard seed and though it be hidden in a rock, or in the heavens or on the earth, God will bring it forth. Truly, God is the knower of all subtleties and He is 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 Do not hold men in contempt, and do not walk with hauteur on the earth. Verily God does not like the proud and boastful. 18 "And be moderate (or show no insolence) in your walking, and lower your voice. Verily, the harshest of all voices is the voice (braying) of the ass." 19
