A precise and accurate sense of where holy sites are located is necessary for many devotional practices. Thus, understanding the extent of these circumstances has a big impact on the Sharia rulings. The land of Karbala is among those where unique regulations have been implemented as a result of the advice of the Infallible (as). Certain unique regulations have been established for several holy sites in this land, such as the Euphrates and Ha’er-i Husseini. These regulations include the advice to take a pilgrimage bath in the Euphrates, the choice to conclude prayers in the Ha’er area or short, among other things. In this case, following these rules requires knowing their exact location. To reach a conclusion between seemingly contradictory narratives regarding the boundaries of these holy places, the author of this study examined the borders of the Haram, Ha'er, and the Euphrates River using an analytical library-based method and jurisprudential and narrative sources. The location of Ha’er-i Husseini (10–12.5 meters from the holy tomb), Haram (up to approximately 35 meters from the holy grave), and the Euphrates (the section that flows through the Karbala region) were determined, which is one of the study’s major findings.
