A group of people went to ask the three brothers of Banu Ghannam for a solution for their complicated question.
As they met the first one, who was an old man, and ask him for a solution, he referred the to his brother saying, "You may find a solution with him because he is older than I am, you can find solution with him".
When they went to meet his brother, they found a middle-aged man. Having sought a solution from him, he said " you may see my third brother and because he is older than I am, you can find solution with him".
Hence they went to the third brother and meet a young looking man. As they could no longer conceal their astonishment, they ask him about his two brother and his manner. " He answered " My brother whom you first met is the youngest among us. Unfortunately, he had to suffer the misbehavior's of his ill-tempered wife because he anticipated an intolerable matter if he would divorce her. His wife therefore has been the main reason beyond his growing old at an earlier time. The second one you met is the middle among us. His wife has gathered both good and bad mannerism. She sometimes pleased him, but she also displeased him. Hence you can see him as middle-aged man. I have a well-mannered wife who never shows misbehavior's with me. Hence I could keep my youth with her.
