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 Luqman advised his son telling him, "My son, do not consider anything equal to God, for it is the greatest injustice." 13 And We have enjoined on man (to be good) to his parents: in travail upon travail did his mother bear him, and in years twain was his weaning: (hear the command), "Show gratitude to Me and to thy parents: to Me is (thy final) Goal. 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 dear son," [continued Luqman,] "verily, if there be but the weight of a mustard-seed, and though it be [hidden] in a rock, or in the skies, or in the earth, God will bring it to light: for, behold, God is unfathomable [in His wisdom,] all-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 "And swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster. 18 "And be moderate (or show no insolence) in your walking, and lower your voice. Verily, the harshest of all voices is the voice (braying) of the ass." 19
