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 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 man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming. 14 If they try to force you to consider things equal to Me, which you cannot justify, equal to Me, do not obey them. Maintain lawful relations with them in this world and follow the path of those who turn in repentance to Me. To Me you will all return and I shall tell you all that you have done. 15 (Lokman said:) 'My son, if it should be but the weight of one grain of mustardseed, and though it be on a rock, or in the heavens, or in the earth, Allah shall bring it. Surely, Allah is the Subtle, Aware. 16 Son, establish Prayer, enjoin all that is good and forbid all that is evil, and endure with patience whatever affliction befalls you. Surely these have been emphatically enjoined. 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 modest in thy bearing and subdue thy voice. Lo! the harshest of all voices is the voice of the ass. 19
