To do this, go to:

app/code/core/Mage/Catalog/Block Folder and copy Navigation.php and override it in your local package.

Open Navigation.php of your package and paste below code in this file:

if ($category->getIsActive()) {
    $cat = Mage::getModel('catalog/category')->load($category->getId());
    $products = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($cat);
    Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($products);
    Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($products);
    Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($products);
    if(count($products)==0)
       return;
}

I hope my code will help you.
