We bestowed wisdom on Luqman, saying, "Be grateful to God: he who is grateful, is grateful only for the good of his own soul. But if anyone is ungrateful, then surely God is self-sufficient and praiseworthy." 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 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 "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 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 do not turn your face away from people in contempt, nor go about in the land exulting overmuch; surely Allah does not love any self-conceited boaster; 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
