If this root ailment is treated and cured, all other maladies flowing from it will also disappear. Such a person having no care for the Aakhirah will not be bothered about righteous deeds nor will he abstain from evil. This is manifest in the Kuffaar . Dunya does not mean wealth and family . Dunya is the intentional and voluntary adoption of anything evil which causes one to become forgetful of Allah Ta'ala irrespective of what that thing may be .
Wealth is like the water in the ocean and the heart of man is like the ship sailing in the ocean .
Water, while it facilitates the movement of the ship can also bring about its sinking. As long as the water remains outside the ship, it aids its sailing. But entry of the water into the ship causes it to sink. Similar is the case of wealth. Wealth aids man as long as it remains outside his heart.
