As a financial obligatory in Islam which is considered as a servitude act, khums (the one fifth of each Muslim's income per year) improves a society's economic development and influences on poverty eradication. There are many issues regarding khums one of which is its decrease after the initial increase. There are two basic opinions in this respect: the majority of jurisprudents' opinion, and Ayatollah Khouei's viewpoint who believes in relative security of khums. Ayatollah Khouei's novelty in this respect has noticeable effects. Investigating these two viewpoints analytically and descriptively based on common jurisprudential methods and analyzing their proofs, this paper maintains that Ayatollah Khouei's opinion is stronger. While investigating theses opinions, the researchers came to this conclusion that relative security of khums is achievable.
