Wadi Rabigh is a wadi situated inland of the town of Rabigh, extending along the border of the al-Madinah and Makkah Regions of Saudi Arabia.
A natural lake near Haggag, some 35 km inland, fringed with reeds and fed by several permanent freshwater springs provides a natural wetland unique on the Tihamah north of Jeddah.
Ghadir Al-Khumm (Arabic غدیر الخم "Pond of Khumm", Persianized Ghadir(-e) Khum, or Khom) is a location in the Wadi Rabigh mentioned in the Hadith of the pond of Khumm.
It was a pond or marsh formed by a spring in the wadi, located to the east of the road from Medina to Mecca, three (according to other sources two) Arab miles (roughly 4 to 6 km) from Al-Johfa (modern Rabigh), roughly 180 km from both Mecca and Medina. The Arab geographers mention the thick trees that surround it and the Mosque of the Prophet lying between it and the spring.
