سورة An-Naml (The Ants ) - الآية 40

The one who had some knowledge of the Book said: I shall bring it unto thee ere thy eye twinkleth. Then when he saw it placed before him, he said: this is of the grace of my Lord that he may prove me whether I give thanks or am ungrateful. Whosoever giveth thanks he only giveth thanks for his own soul; and whosoever is ungrateful then verily my Lord is Self-sufficient, Munificent.
