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 [mention, O Muhammad], when Luqman said to his son while he was instructing him, "O my son, do not associate [anything] with Allah. Indeed, association [with him] is great injustice." 13 And We charged the human concerning his parents, for his mother bore him in weakness upon weakness, and his weaning was in two years. Be thankful to Me and to your parents, to Me is the arrival. 14 "But if they strive to make thee join in worship with Me things of which thou hast no knowledge, obey them not; yet bear them company in this life with justice (and consideration), and follow the way of those who turn to me (in love): in the end the return of you all is to Me, and I will tell you the truth (and meaning) of all that ye did." 15 O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, 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 (contemptuously) turn your face away from people, nor tread haughtily upon earth. Allah does not love the arrogant and the vainglorious. 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
