ecessity of some cases of financial payments in Islam are in dispute among jurisprudents and in spite of existence of Quranic and traditional reasons about the obligation of some of them like “Known Right”, mostly all jurisprudents have pronounced that they are not necessary. Examining of their evidences shows that the most important reason for the justification of their verses and traditions and so their non necessity are traditions that their contents are limited to alms. Thus, for this reason the lawfulness of taxes has been doubted, too. This research shows that mentioned traditions are weak in respect of their chain and denotation and can not be relied on for decree. So, quoted traditions from Shiite and Sunni sources have been considered in chain and denotation.
