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 And We have enjoined man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming. 14 But if they strive with thee to make thee ascribe unto Me as partner that of which thou hast no knowledge, then obey them not. Consort with them in the world kindly, and follow the path of him who repenteth unto Me. Then unto Me will be your return, and I shall tell you what ye used to do - 15 "O my son, whatsoever it may be, even though equal to a mustard seed in weight, or within a rock or in the sky or in the earth, God will bring it forth. Verily God is perceptive, all-aware. 16 “O my son! Keep the prayer established, and enjoin goodness and forbid from evil, and be patient upon the calamity that befalls you; indeed these are acts of great courage.” 17 “And do not contort your cheek while talking to anyone, nor boastfully walk upon the earth; indeed Allah does not like any boastful, haughty person.” 18 And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys." 19
