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 We have enjoined man to show kindness to his parents -- for his mother bears him, in hardship upon hardship, and his weaning takes two years. [We said] Give thanks to Me and to your parents; all will return to Me. 14 But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with appropriate kindness and follow the way of those who turn back to Me [in repentance]. Then to Me will be your return, and I will inform you about what you used to do. 15 "O my son!" (said Luqman), "If there be (but) the weight of a mustard-seed and it were (hidden) in a rock, or (anywhere) in the heavens or on earth, Allah will bring it forth: for Allah understands the finest mysteries, (and) is well-acquainted (with them). 16 “O my son! Keep the prayer established, and enjoin goodness and forbid from evil, and be patient upon the calamity that befalls you; indeed these are acts of great courage.” 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 “And walk moderately and soften your voice; indeed the worst voice is the voice of the donkey.” 19
