The Hill of Arafat is also known as Jabal ar-Rahmah, meaning Mountain of Mercy. On the ninth day of hajj, pilgrims leave Mina for Mount Arafat where they stand in contemplative vigil and pray and recite the Qur’an. It is here that Prophet Muhammad (may the blessings and peace of Allah be upon him) gave his last sermon to the Muslims who had accompanied him for the Hajj towards the end of his life. A pilgrim’s Hajj is considered invalid if they do not spend the afternoon on Mount Arafat.
Zam ZamWell
Allah (the Glorified and Exalted) created the well to provide Hajira, the wife of Prophet Ibrahim (Abraham) (peace be upon him), and her baby Prophet Ismail (Ishmael) (peace be upon him) with water in the hot, dry valley they were in, around the year 2000 BC. In her desperate search for water, Hajira ran seven times back and forth in the scorching heat between the two hills of Safa and Marwa to provide for her baby who was dying of thirst. The Zamzam Well is located approximately 20 m (66 ft) east of the Kaaba.
