and, indeed, we granted this wisdom unto Luqman: "Be grateful unto God - for he who is grateful [unto Him] is but grateful for the good of his own self; whereas he who chooses to be ungrateful [ought to know that,] verily, God is self-sufficient, ever to be praised!" 12 (Remember) when Luqman counselled his son: "O son, do not associate any one with God. To associate others with God is a grievous wrong." 13 And We have enjoined upon man concerning his partners - His mother beareth him in weakness upon weakness, and his weaning is in two years - Give thanks unto Me and unto thy parents. Unto Me is the journeying. 14 But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do. 15 [Luqman further said,] "O my son! Though it be but the weight of a grain of mustard seed and though it be hidden in a rock, or in the heavens or on the earth, God will bring it forth. Truly, God is the knower of all subtleties and He is aware. 16 "O my dear son! Be constant in prayer, and enjoin the doing of what is right and forbid the doing of what is wrong, and bear in patience whatever [ill] may befall thee: this, behold, is something to set one's heart upon! 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 be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys." 19
