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, and he used to advise him, “O my son! Never ascribe anything as a partner to Allah; indeed ascribing partners to Him is a tremendous injustice.” 13 And We have enjoined upon man [care] for his parents. His mother carried him, [increasing her] in weakness upon weakness, and his weaning is in two years. Be grateful to Me and to your parents; to Me is the [final] destination. 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! 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! establish prayer and command that which is reputable and forbid iniquity, and bear patiently whatsoever may befall thee; verily that is of the firmness of affairs. 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 Be modest in thy walk, and lower thy voice; the most hideous of voices is the ass's.' 19
