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 Lokman said to his son, in warning: 'My son, associate none with Allah, to associate others with Allah is a tremendous wrong' 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 But if they press you to associate others with Me in My Divinity, (to associate) those regarding whom you have no knowledge (that they are My associates), do not obey them. And yet treat them well in this world, and follow the way of him who turns to Me in devotion. Eventually it is to Me that all of you shall return, and I shall then tell you all that you did.” 15 O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware; 16 O my son, fulfil your moral obligations, bid what is known to be right and forbid what is wrong, and bear with patience what befalls you. These are indeed acts of courage and resolve. 17 Turn not thy cheek in scorn toward folk, nor walk with pertness in the land. Lo! Allah loveth not each braggart boaster. 18 “And walk moderately and soften your voice; indeed the worst voice is the voice of the donkey.” 19
