We bestowed wisdom on Luqman, saying, "Be grateful to God: he who is grateful, is grateful only for the good of his own soul. But if anyone is ungrateful, then surely God is self-sufficient and 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 upon man concerning his parents - his mother beareth him in hardship upon hardship and his weaning is in two years: give thanks unto Me and unto thy parents; unto Me is the goal. 14 But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with appropriate kindness and follow the way of those who turn back to Me [in repentance]. Then to Me will be your return, and I will inform you about what you used to do. 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 My son, establish the prayer, order with honor but forbid dishonor, and bear patiently with whatever may fall upon you, indeed that is true constancy. 17 Do not avert your face from people out of haughtiness and do not walk with pride on the earth: for, behold, God does not love arrogant and boastful people. 18 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
