Said one who had knowledge of the Book : " I will bring it to thee within the twinkling of an eye ! " Then when ( Solomon ) saw it placed firmly before him , he said : " This is by the Grace of my Lord ! - to test me whether I am grateful or ungrateful ! and if any is grateful , truly his gratitude is ( a gain ) for his own soul ; but if any is ungrateful , truly my Lord is Free of all Needs , Supreme in Honour !
