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 ordained upon man concerning his parents; his mother bore him enduring weakness upon weakness, and his suckling is up to two years – therefore be thankful to Me and to your parents; finally towards Me is the return. 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, if it should be but the weight of one grain of mustard-seed, and though it be in a rock, or in the heavens, or in the earth, God shall bring it forth; surely God is All-subtle, All-aware. 16 O my dear son! Say your prayers regularly, and enjoin good, and forbid evil, and endure patiently whatever may befall you. Surely, this is something which requires firm resolve. 17 And do not turn your cheek [in contempt] toward people and do not walk through the earth exultantly. Indeed, Allah does not like everyone self-deluded and boastful. 18 Be moderate in your stride and lower your voice. Verily the most disgusting of all voices is the braying of the donkey.” 19
