Musannaf Ibn Abi Shayba 23:179

Al-Hasan ibn Musa narrated to us, he said: Hammad ibn Salamah narrated to us, from Asim ibn Bahdalah, from al-Musayyab ibn Rafi, from Kharashah ibn al-Hurr, who said: I arrived in Medina and sat with some elders in the mosque, the companions of the Messenger of Allah, may Allah bless him and grant him peace. He said: Then an old man came, leaning on a staff of his. The people said, "Whoever is pleased to look at a man from the people of Paradise, let him look at this one." He said: So he stood behind a pillar and prayed two rak'ahs. I stood up to him and said to him, "Some of the people said such and such." He said: "Praise be to Allah. Paradise belongs to Allah; He admits into it whom He wills. I saw a vision during the time of the Messenger of Allah, may Allah bless him and grant him peace. I saw as if a man came to me and said, 'Come with me.' So I went with him, and he led me along a great path. A road appeared to me on my left, and I wanted to take it, but it was said, 'You are not of its people.' Then a road appeared to me on my right, and I took it until I reached a slippery mountain. He took my hand and climbed with me until I was at its peak. I could not steady myself or hold on, and there was an iron pillar at its peak with a ring of gold. He took my hand and climbed with me, and I took hold of the handle. He said, 'Hold fast.' I said, 'Yes.' Then he kicked the pillar with his foot, and I held fast to the handle." "I narrated this to the Messenger of Allah, may Allah bless him and grant him peace, and he said: 'You have seen good. As for the great path, it is the Gathering Place (al-Mahshar). As for the road that appeared to your left, it is the path to the Fire, and you are not of its people. As for the road that appeared to your right, it is the path of the people of Paradise. As for the slippery mountain, it is the station of the martyrs. As for the handle you held onto, it is the handle of Islam, so hold fast to it until you die.'" He said: "And I hope that I am one of the people of Paradise." He said: And he was Abdullah ibn Salam.
