The refusal to give what is obliged according to sacred law or to virtuous merit
Obligations of sacred law
Zakat
Supporting one's dependents
Rights due to others
Relieving the distressed
Virtuous merit
Not nitpicking over trivialities
Avoiding miserliness is more important
With respect to a neighbor, a relative, or a wealthy person
When hosting guests
Concerning something in which such behavior is inappropriate, such as purchasing a burial shroud or a sacrificial animal, or purchasing something you intend to donate to the needy
One who makes matters difficult for one whose rights clearly render this inappropriate to do so, such as a neighbor, has indeed torn away the veils of dignity
This is comparable to one who fulfills his obligations without good cheer or who spends from the least of what he possesses
Root of miserliness
Love of this world for its own sake, or so that the self can acquire some of its fleeting pleasures
Miser
Unable to let go of something that otherwise poisons them
The worst person is the miser. In this world, he is deprived of his own wealth, and in the Hereafter, he is punished
Treatment for miserliness
1. Realizing that those who achieve wealth usually do so only after exhausting themselves over long periods of time
2. Recognizing that just as people climb the heights of affluence, death assails them
3. Realizing the disdain and hatred shown to misers
The treatment for miserliness also applies to the person whose heart's ailment is love of wealth
