Riyad Us-Saliheen (Gardens of the Righteous)

Chapter 270
Prohibition of Envy

Allah, the Exalted, says:

"Or do they envy men (Muhammad (PBUH) and his followers) for what Allah has given them of His Bounty?'' (4:54)

1569.  Abu Hurairah (May Allah be pleased with him) said: The Prophet (PBUH) said, "Beware of envy because envy consumes (destroys) the virtues just as the fire consumes the firewood,'' or he said "grass.''
[Abu Dawud].

Commentary:  Envy is one of the major sins which are bound to destroy virtues as fast as the fire burns the wood and dry grass to ashes.
