From Ibn 'Abbaas (RA) who said that Allaah’s Messenger (SAW) said: There are two blessings which many people lose: health and free time.
Reported by al-Bukharee (Eng. Trans. 8/282/no.421)
“I put my trust in Allah, my Lord and your Lord! There is not a moving creature, but He has a grasp of its forelock. Verily, my Lord is on the straight path. (The truth)”
(11:55-56)
