Then a Sura says, "Verily, man is cruel and foolish." Foolish, because he has taken upon himself that which is God's. There are many who run away from marriage, because they think that a wife and children are a responsibility. They do not think that wife and children are God's and that He takes care of what is His. Cruel, because he uses his will and strength -- which are God's -- to harm others. Our will, our strength are God's, and yet we say " my" and " mine;" we claim them for ourselves.
