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 Lokman said to his son, in warning: 'My son, associate none with Allah, to associate others with Allah is a tremendous wrong' 13 We have committed man about his parents. His mother carries him in her womb in weakness and debility, weaning him in two years. So he should be grateful to Me and his parents. To Me is the journeying back. 14 "'[Revere thy parents;] yet should they endeavour to make thee ascribe divinity, side by side with Me, to something which thy mind cannot accept [as divine,] obey them not; but [even then] bear them company in this world's life with kindness, and follow the path of those who turn towards Me. In the end, unto Me you all must return; and thereupon I shall make you [truly] understand all that you were doing [in life].' 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 dear son! Establish worship and enjoin kindness and forbid iniquity, and persevere whatever may befall thee. Lo! that is of the steadfast heart of things. 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
