Yazid bin Abi Sawrah says: I saw Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him); he was on the wall of the mosque at that time, with his chest resting on it, and he was weeping as he looked down towards the Valley of Jahannam (a place by that name). I said: "O Abu al-Walid, why are you weeping?" He said: "This is the place about which the Prophet (peace and blessings be upon him) told us that he (peace and blessings be upon him) saw Hell here."
Al-Tabarani recorded it. I do not know the narrator Yazid, and this narration contains weak narrators who have been declared trustworthy.
