Abstract Verdicts of Sharia law have conditioned the majority of issues such as marja’iyyat or source of religious authority, adjudication, leadership of Friday and congregation prayers, testimony bearing,… to justice. In their definition of justice, the majority of contemporary jurists have validated manliness in addition to such preconditions as lack of committing mortal sins and no intention of committing venial sins. A person acting against manliness and humanity lacks required competence to take the aforesaid responsibility. In this paper, developed through analytical-descriptive method, we have tried to precisely clarify the meaning of manliness and its effects while analyzing jurisprudential fundamentals for subjecting justice to manliness and the differences of jurist opinions on the subject. Finally, we have reviewed in detail Imam Khomeini’s views on the status of manliness in justice of the witness.k
