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 [mention, O Muhammad], when Luqman said to his son while he was instructing him, "O my son, do not associate [anything] with Allah. Indeed, association [with him] is great injustice." 13 And We ordained upon man concerning his parents; his mother bore him enduring weakness upon weakness, and his suckling is up to two years – therefore be thankful to Me and to your parents; finally towards Me is the return. 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 [And Luqman said], "O my son, indeed if wrong should be the weight of a mustard seed and should be within a rock or [anywhere] in the heavens or in the earth, Allah will bring it forth. Indeed, Allah is Subtle and Acquainted. 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 away thy cheek from men nor walk on the earth stultingly, verily Allah loveth not any vainglorious boaster. 18 Be modest in thy bearing and subdue thy voice. Lo! the harshest of all voices is the voice of the ass. 19
