Nahjul Balagha Letter 49

To Muawiya

This world turns away from the next one. Its devotee achieves nothing from it except it increases his greed and coveting for it. Its devotee is not satisfied with what he gets from it because of what he has not got. Eventually, there is separation from what has been amassed, and breaking of what has been strengthened. If you take lessons from the past, you can be safe in the future.
