It is narrated from Hazrat Imran Ansari that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) came to me while I had stopped under a tree on the way to Makkah. He asked: Why did you stop under this tree? I said: For shade. He asked: For any other reason? I said: No, I only stopped for shade. Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) said: "When you reach Mina between the two mountains (and he gestured with his hand towards the east), there is a place called Sarar, there is a tree under which the sandals of seventy Prophets were cut, or seventy Prophets received Prophethood." Thus, he was pleased because of this.
