We gave wisdom to Luqman so that he would give thanks to God. Those who give thanks to God do so for their own good. Those who are ungrateful should know that 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 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 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 [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 swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant 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
