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 have charged man concerning his parents -- his mother bore him in weakness upon weakness, and his weaning was in two years -- 'Be thankful to Me, and to thy parents; to Me is the homecoming. 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, 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 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 Do not turn your cheek in scorn away from people, nor walk proudly on the earth; Allah does not love the proud and the boastful. 18 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
