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 when Luqman said to his son while he admonished him: O my son! do not associate aught with Allah; most surely polytheism is a grievous iniquity-- 13 And We ordained upon man concerning his parents; his mother bore him enduring weakness upon weakness, and his suckling is up to two years – therefore be thankful to Me and to your parents; finally towards Me is the return. 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 O my dear son! Lo! though it be but the weight of a grain of mustard-seed, and though it be in a rock, or in the heavens, or in the earth, Allah will bring it forth. Lo! Allah is Subtile, Aware. 16 O my son! keep up prayer and enjoin the good and forbid the evil, and bear patiently that which befalls you; surely these acts require courage; 17 Do not turn your cheek in scorn away from people, nor walk proudly on the earth; Allah does not love the proud and the boastful. 18 Be modest in thy bearing and subdue thy voice. Lo! the harshest of all voices is the voice of the ass. 19
