Musnad Ahmad 1255:12

'Affan narrated to us, Hammad bin Salamah narrated to us, he said: Dawud informed us, from 'Amir, from Fatimah bint Qays, that the Prophet, may God bless him and grant him peace, came one day in a hurry, so he ascended the pulpit, and it was called out among the people: "Prayer is gathering," so the people gathered. He said: "O people, I did not call you for a desire that has descended, nor for a fear, but Tamim al-Dari informed me that people from the people of Palestine boarded the sea, and the wind cast them onto an island of the islands of the sea. There, they found a beast, hairy, it is not known whether it is male or female due to the abundance of its hair. They said: 'Who are you?' It said: 'I am the Jassasah.' They said: 'Inform us.' It said: 'I will not inform you, nor will I ask you, but in this monastery is a man who is eager to inform you and ask you.' So they entered the monastery, and there was a man, shackled in iron. He said: 'Who are you?' We said: 'We are the Arabs.' He said: 'Has the Prophet been sent among you?' We said: 'Yes.' He said: 'Have the Arabs followed him?' They said: 'Yes.' He said: 'That is better for them.' He said: 'What has Persia done? Has he prevailed over it?' They said: 'He has not prevailed over it yet.' He said: 'As for it, he will prevail over it.' Then he said: 'What has the spring of Zughar done?' They said: 'It is flowing, full.' He said: 'And what has the Lake of Tiberias done?' They said: 'It is flowing, full.' He said: 'And what has the palm tree of Baysan done? Has it borne fruit yet?' They said: 'Its early ones have borne fruit.' He said: 'Then he leaped a leap, and we thought he would escape. We said: 'Who are you?' He said: 'I am the Dajjal. As for me, I will tread the entire earth except for Makkah and Taybah.'" The Messenger of God, may God bless him and grant him peace, said: "Rejoice, O company of Muslims, for this is Taybah, and the Dajjal shall not enter it."
