Maqaam-e-Ishmael
This is the spot where the Abraham (AS) took Ishmael (AS) to be slaughtered. At the time when Abraham was about to use his knife, the Angel Gabriel appeared with a lamb, which was then sacrificed when God pardoned Ishmael and Abraham. The Muslim festival of Eid-ul-Adha is celebrated in remembrance of this act. It is also the inspiration for the Hadi or a sacrifice as part of the Hajj on the 10 Zill Hajja. Unfortunately, the access to this spot is restricted due to the Royal Palace that has been built around the hill. Try your luck still, you just might find a sympathetic ear.
