An Imam is about to walk into the musallah to give a khutbah when he runs into some small children. Being well mannered little boys and girls, they give the Imam the salaams, and he returns them."Now, children" the Imam says "You know that you must be quiet while the khutbah is being given, don't you?" The children all say yes. "Alhamdulillah! Very good. Now, who can tell me why you have to be quiet during the khutbah?"Little Ahmed raises his hand and says "Because people are trying to sleep!"
