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 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 press you to associate others with Me in My Divinity, (to associate) those regarding whom you have no knowledge (that they are My associates), do not obey them. And yet treat them well in this world, and follow the way of him who turns to Me in devotion. Eventually it is to Me that all of you shall return, and I shall then tell you all that you did.” 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 son! establish regular prayer, enjoin what is just, and forbid what is wrong: and bear with patient constancy whatever betide thee; for this is firmness (of purpose) in (the conduct of) affairs. 17 "And turn not thy cheek away from people in [false] pride, and walk not haughtily on earth: for, behold, God does not love anyone who, out of self-conceit, acts in a boastful manner. 18 Be modest in thy walk, and lower thy voice; the most hideous of voices is the ass's.' 19
