Narrated Ibn Abbaas (radiyallaahu-anhuma): The Prophet (sallal-laahu-alayhi-wasallam) said: ”There are two blessings which many people lose: (They are) health and free time for doing good.”
Imaam Abdul-Azeez Bin Baaz (rahimahullaah) said: This is the true state of affairs. Many people are deprived of these two blessings. (They) depart from him (i.e. the person) without fruitful gain and that is: They depart from him without (him acquiring) any benefit.
