He who gives thanks, thanks only for himself, but whosoever is ungrateful, surely, Allah is the Rich, the Praised' 12 Luqman advised his son telling him, "My son, do not consider anything equal to God, for it is the greatest injustice." 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 strive to make thee join in worship with Me things of which thou hast no knowledge, obey them not; yet bear them company in this life with justice (and consideration), and follow the way of those who turn to me (in love): in the end the return of you all is to Me, and I will tell you the truth (and meaning) of all that ye did." 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 Son, establish Prayer, enjoin all that is good and forbid all that is evil, and endure with patience whatever affliction befalls you.
