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 recall what time Luqman said unto his son, while he was exhorting him: O my son! associate not aught with Allah; verily this associating is surely a tremendous wrong. 13 And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents, unto Me is the final destination. 14 And if the twain strive with thee to make thee associate with Me that for which thou hast no knowledge, then obey them not. And bear them thou company in the world reputably, and follow thou the path of him who turneth penitently unto Me. Then unto Me is your return, and I shall declare unto you that which ye have been working. 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 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 scornfully turn your face away from people. Do not walk around puffed-up with pride; God does not love arrogant and boastful people. 18 "And be moderate in thy pace, and lower thy voice; for the harshest of sounds without doubt is the braying of the ass." 19
