We gave wisdom to Luqman so that he would give thanks to God. Those who give thanks to God do so for their own good. Those who are ungrateful should know that 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 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 strive with thee to make thee associate with Me that whereof thou hast no knowledge, then do not obey them. Keep them company honourable in this world; but follow the way of him who turns to Me. Then unto Me you shall return, and I shall tell you what you were doing.') 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, perform the prayer, and bid unto honour, and forbid dishonour. And bear patiently whatever may befall thee; surely that is true constancy. 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
