Such routes are known in Arabic as "Wadi" (valley).
Such routes are known in Arabic as "Wadi" (valley). Thus, in depiction of Ghadir in geographical terms, we can say: The Johfah valley is an inundated route that leads into the sea. On this route a natural pool has emerged where in the post flood period, water collects in such a pool. Such a pool is called 'Ghadir' in Arabic. At various places, there exist many Ghadirs in the course of flowing floods and each one is distinguished from the other by a specific name.
In order to be distinguished from the others, this 11 Mataleb ol-Navaseb (Ibne Shahr-Aashoub), p. 63 Ghadir too has been given a name viz, Ghadir-Khum. The name of Ghadir Khum has' remained unchanged during the last fourteen centuries and in the historical and geographical books and dictionaries, his name has been used for this specific place throughout the centuries.
The exact position of this place has also been determined and the distances from all four sides of this place have been clearly stated. In this regard, one can refer to the following books: Mu'jam Mastu'jem, Vo12, p. 368,492, and 510 Lisan aI-Arab, word Khamam and Ghadar Mu'jam al-Holdan, Vol 2, p 350, 389, Vol 3, p 159, Vol 4, p 188, V 01 6, word Ghadir. Mu'jam Ma'alem al-Hejaz, Voll, p 156 Taj al-Aroos, word Khamam and Ghadar. Al-Nihayah (Ibne-Athir), word Khamam.
Al-Rauzal Ma'thar, Vol156 Wafa al-Wafa, Vo12, p 298 Sefato Jazirat-ul Arab, p 259 Taking into consideration that a geographical territory is known as various names on different grounds, GhadirKhum too has been called by different territorial names in history from geographical aspects. In some cases it is remembered as "Johfeh" because it is located in the Johfeh valley. In other cases it is called as "Kharrar" which is the name of the route the floods flow from Ghadir to Johfeh.
In other instances, it was called as "Ghorabeh", because it is the name of a territory adjacent to Ghadir Khum, and both of these are located in the same valley. Considering that Ghadir and Johfeh lie from East to West, in flood flowing region, the more it proceeds towards the sea, it becomes winder. . People, who wanted to determine the distance from Johfeh to Ghadir, have measured the distance from different angles.
Thus, the distance till Johfeh has been measured as three miles, and at times two miles. On the other side, with the passage of time, the geographical condition of the region has changed, especially considering that the area is an inundated region.
