And certainly We gave wisdom to Luqman, saying: Be grateful to Allah. And whoever is grateful, he is only grateful for his own soul; and whoever is ungrateful, then surely Allah is Self-sufficient, Praised. 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 "'[Revere thy parents;] yet should they endeavour to make thee ascribe divinity, side by side with Me, to something which thy mind cannot accept [as divine,] obey them not; but [even then] bear them company in this world's life with kindness, and follow the path of those who turn towards Me. In the end, unto Me you all must return; and thereupon I shall make you [truly] understand all that you were doing [in life].' 15 O my son! 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 shall bring it forth. Verily 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 And do not turn your face away from people in contempt, nor go about in the land exulting overmuch; surely Allah does not love any self-conceited boaster; 18 Walk modestly, and lower your voice; the most hideous of voices is the braying of the donkey. 19
