It is narrated from Sayyiduna Imran Ansari, he says: I was staying under a large tree on the way to Makkah when Sayyiduna Abdullah bin Umar (may Allah be pleased with him) came to me and asked: Why are you staying under this tree? I said: I have stopped here merely to rest in its shade. He asked: Is there any other purpose besides this? I said: No, I am only staying here to rest in the shade. He said: The Messenger of Allah (peace and blessings be upon him) said that when you reach Mina between the two mountains, and then he pointed towards the east and said: There is a valley there, which is called the Valley of Sarr, in which there is a large tree, under which seventy Prophets were born and their umbilical cords were cut there.
