It is believed that in this mausoleum, located in the southwestern city of Susa in Iran, is the tomb of Prophet Danyal [Daniel] (peace be upon him). He is best known for having spent time in the lion’s den.
Ibn Abi Al-Dunya recounts the following, based on a chain of quotes:
Nebuchadnezzar (Bakht Nasr) caught two lions and threw them into the pit. Then he brought Danyal (peace be upon him) and also threw him, but the lions did not attack him. He stayed there as long as Allah willed him to stay there, and then he felt the need to eat and drink. So, Allah revealed to Armiya (peace be upon him) [Jeremiah], who was in Beit al-Maqdis, to prepare food for Danial, who was in Babylon, Iraq.
When he prepared the meal, Allah carried it with a meal to Danial. There he told him that Allah had asked him to deliver food to him, and he noted that indeed Allah remembered him, and he praised Allah greatly for the many favours he had bestowed on him. He ended his praise with the words: “Praise be to Allah, Who is our hope, when all hopes are cut off from us.”
The above scene is known locally as Aramgah-e-Danyal.
The Jews disagree that Daniel (peace be upon him) is a prophet.
