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 Luqman advised his son telling him, "My son, do not consider anything equal to God, for it is the greatest injustice." 13 "And [God says:] 'We have enjoined upon man goodness towards his parents: his mother bore him by bearing strain upon strain, and his utter dependence on her lasted two years: [hence, O man,] be grateful towards Me and towards thy parents, [and remember that] with Me is all journeys' end. 14 But if they strive with thee to make thee associate with Me that whereof thou hast no knowledge, then do not obey them. Keep them company honourable in this world; but follow the way of him who turns to Me. Then unto Me you shall return, and I shall tell you what you were doing.') 15 O my son! though it be but the weight of a grain of mustard-seed, and though it be in a rock or in the heavens, or in the earth, Allah shall bring it forth. Verily Allah is subtile, Aware. 16 My son, establish the prayer, order with honor but forbid dishonor, and bear patiently with whatever may fall upon you, indeed that is true constancy. 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 Walk modestly, and lower your voice; the most hideous of voices is the braying of the donkey. 19
