Indeed, We gave Lokman wisdom: 'Give thanks to God. Whosoever gives thanks gives thanks only for his own soul's good, and whosoever is ungrateful -- surely God is All-sufficient, All-laudable.' 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 ordained upon man concerning his parents; his mother bore him enduring weakness upon weakness, and his suckling is up to two years – therefore be thankful to Me and to your parents; finally towards Me is the return. 14 If they try to force you to consider things equal to Me, which you cannot justify, equal to Me, do not obey them. Maintain lawful relations with them in this world and follow the path of those who turn in repentance to Me. To Me you will all return and I shall tell you all that you have done. 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, perform the prayer, and bid unto honour, and forbid dishonour. And bear patiently whatever may befall thee; surely 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
