Jabal Ayr (Mount Ayr) is the second largest mountain in Madinah after Uhud and marks the southern boundary of Madinah. The Prophet (ﷺ) described it as a mountain of Hell.
- The Prophet (ﷺ) declared, “Uhud is a mountain which loves us and which we love, it is upon the Gate of Heaven” adding, “And Ayr is a place which hates us and which we hate, it is upon the Gate of Hell.”
- ‘Ayr’ means a ‘wild ass’, whereas Uhud is derived from Ahad, meaning ‘one’, — so called because it is fated to be the place of victory to those who worship one God. The very names, say Muslim sages, make it abundantly evident that even as the men of Al-Madinah were of two parties, friendly and hostile to the Prophet (ﷺ), so were these mountains.
