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 But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do. 15 O my dear son! Lo! though it be but 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. Lo! Allah is Subtile, Aware. 16 Son, establish Prayer, enjoin all that is good and forbid all that is evil, and endure with patience whatever affliction befalls you. Surely these have been emphatically enjoined. 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 modest in thy walk, and lower thy voice; the most hideous of voices is the ass's.' 19
