Indeed, We gave Lokman wisdom: 'Give thanks to God. Whosoever gives thanks gives thanks only for his own soul's good, and whosoever is ungrateful -- surely God is All-sufficient, All-laudable.' 12 Luqman advised his son telling him, "My son, do not consider anything equal to God, for it is the greatest 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! 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 O My son! establish prayer and command that which is reputable and forbid iniquity, and bear patiently whatsoever may befall thee; verily that is of the firmness of affairs. 17 And turn not away thy cheek from men nor walk on the earth stultingly, verily Allah loveth not any vainglorious boaster. 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
