The ultimate goal of Islam is to cultivate a mature human being who is devoid of either psychological or emotional coarseness. Inspection of murder cases have shown that many of them have happened because of honor motivations. Treachery among married couples, sexual deviation, doubt, pessimism, deviations in childhood and puberty, fault, and unrestrainedly were regarded as the reasons of chastity-related murders. The aim of this study was to investigate the role of religion and Islam doctrines in preventing chastity-related murders. Based on the results of the study, it was shown that Islam, its doctrines and particularity about the doctrines has the power to prevent chastity- related murders. The observation of religious standards including: creating a well-founded behavioral situation in families, respecting Hejab (Veil), modesty, virtue, avoiding the commitment of suspicion, unlawful morsel, unlawful eyeing, certainty of chastity, observation of sexual behavior, respecting marital duties (including: apparent adornment, holding trust, good environment, choosing the proper spouse, etc) are all regarded as the main issues which can prevent chastity-related murders. This was a qualitative study in which various research tools were used. Participation, interview, direct observation, note-taking, and analyzing different documents were the research tools.
