We gave wisdom to Lokman (saying): 'Give thanks to Allah. He who gives thanks, thanks only for himself, but whosoever is ungrateful, surely, Allah is the Rich, the Praised' 12 Luqman advised his son telling him, "My son, do not consider anything equal to God, for it is the greatest 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 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! If it be (anything) equal to the weight of a grain of mustard seed, and though it be in a rock, or in the heavens or in the earth, Allah will bring it forth. Verily, Allah is Subtle (in bringing out that grain), Well-Aware (of its place). 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 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
