Uryan bin al-Haytham narrates: I went to Yazid bin Mu'awiyah. While we were sitting with him, a man came to him, took his cushion and leaned on it. We asked: "Who is this gentleman?" Someone said: "This is Sayyiduna Abdullah bin Amr (may Allah be pleased with him)." One of us said: "O Sayyiduna Abdullah bin Amr (may Allah be pleased with him)! We keep hearing hadiths reported from you." He said: "O people of Iraq, you take hadith from those at the bottom and do not take it from those at the top." The people mentioned the Dajjal, so Sayyiduna Abdullah bin Amr (may Allah be pleased with him) asked: "Is there a place in your land called 'Kutha', a salty marshland with date palms?" We replied: "Yes." So Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: "The Dajjal will emerge from there."
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy).
