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 And (remember) when Luqman said to his son when he was advising him: "O my son! Join not in worship others with Allah. Verily! Joining others in worship with Allah is a great Zulm (wrong) indeed. 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 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 O my dear son! Say your prayers regularly, and enjoin good, and forbid evil, and endure patiently whatever may befall you. Surely, this is something which requires firm resolve. 17 Do not hold men in contempt, and do not walk with hauteur on the earth. Verily God does not like the proud and boastful. 18 "And be moderate (or show no insolence) in your walking, and lower your voice. Verily, the harshest of all voices is the voice (braying) of the ass." 19
