critical study on increasing blood money for murder commitment in haram months (religiously-prohibited months)

according to commonly believed in imamiyeh' s fiqh, a murder commitment made in haram months would causes an increment in blood money to one third. the increment is called taghlize diyeh, increase of blood money. the increase includes all three kinds of murder commitments, namely intentional, quasi-intentional and unintentional ones, the very meaning written down in islamic puni-shment law. it should be stated that though the four months have been judged according to quran to be forbidden, the problem of taghliz is not mentioned in quran. this paper has deeply studied the traditions of taghliz and argued that we cannot find any clear designation for taghliz in unintentional murder. in addition, as it is clear that unintentional murders do not break any prohibition, the pen has concluded that taghliz is limited to intentional and quasi-intentional murders and does not include unintentional murder.
