"The Messenger (SAW) said: “Whoever rises in the morning and is in good health, secure and has the day’s food, it is as though he has the whole world.’"
"One day the Messenger (SAW) was looking at the sky. He laughed and said: “I remain astonished at the decree of God Most High with regard to the believer. If he commands a blessing, he is content that it is for his good; and if He commands an affliction, he is content that it is for his good.” That is, he suffers the latter and is grateful for the former because there is always goodness in both. And the Messenger said: “The healthy will wish at the Resurrection that their flesh had been cut away with the talons of a leather currier out of pique for seeing the many high degrees of the afflicted”."
