Indeed, We gave Lokman wisdom: 'Give thanks to God. Whosoever gives thanks gives thanks only for his own soul's good, and whosoever is ungrateful -- surely God is All-sufficient, All-laudable.' 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 (Concerning his parents), We advised the man, whose mother bears him with great pain and breast-feeds him for two years, to give thanks to Me first and then to them, to Me all things proceed. 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 [And Luqman said], "O my son, indeed if wrong should be the weight of a mustard seed and should be within a rock or [anywhere] in the heavens or in the earth, Allah will bring it forth. Indeed, Allah is Subtle and Acquainted. 16 O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination. 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 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
