The benefits of charity are better in both the worlds. A generous person is respected everywhere, while a miser is insulted in both the worlds.
In praise of charity, suffice is to say, that Hatimtai will be protected from the heat of the fire of hell as stated by the Holy Prophet (s.a.w.a.) to his son Adi.
Son! Miserliness brings disgrace in this world as well as hereafter. But beware! Your generosity should not be such that you are left bankrupt.
Adopt the middle path. Find your way of life between miserliness and squandering.
