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 And when Luqman said to his son while he admonished him: O my son! do not associate aught with Allah; most surely polytheism is a grievous iniquity-- 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 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," [continued Luqman,] "verily, if there be but the weight of a mustard-seed, and though it be [hidden] in a rock, or in the skies, or in the earth, God will bring it to light: for, behold, God is unfathomable [in His wisdom,] all-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 your face away from men with pride, nor walk in insolence through the earth. Verily, Allah likes not each arrogant boaster. 18 Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's." 19
