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 (remember) when Luqman said unto his son, when he was exhorting him: O my dear son! Ascribe no partners unto Allah. Lo! to ascribe partners (unto Him) is a tremendous wrong - 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 press you to associate something with Me about which you have no knowledge, do not obey them. Yet be kind to them in this world and follow the path of those who turn to Me. You will all return to Me in the end, and I will tell you everything that you have done. 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 "And turn not your face away from men with pride, nor walk in insolence through the earth. Verily, Allah likes not each arrogant boaster. 18 Be modest in thy walk, and lower thy voice; the most hideous of voices is the ass's.' 19
