And indeed We bestowed wisdom to Luqman (saying) that, “Be grateful to Allah”; and whoever is grateful, is grateful for his own good; and whoever is ungrateful – then indeed Allah is the Absolute, the Most Praiseworthy. 12 And recall what time Luqman said unto his son, while he was exhorting him: O my son! associate not aught with Allah; verily this associating is surely a tremendous wrong. 13 And We have enjoined man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming. 14 And if they contend with you that you should associate with Me what you have no knowledge of, do not obey them, and keep company with them in this world kindly, and follow the way of him who turns to Me, then to Me is your return, then will I inform you of what you did-- 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 “O my son! Keep the prayer established, and enjoin goodness and forbid from evil, and be patient upon the calamity that befalls you; indeed these are acts of great courage.” 17 “And do not contort your cheek while talking to anyone, nor boastfully walk upon the earth; indeed Allah does not like any boastful, haughty person.” 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
