Musnad Abi Ya'la 2178 — one day the Messenger of Allah ﷺ stood

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that one day the Messenger of Allah (peace and blessings be upon him) stood on the pulpit and said: "Some people were travelling on the sea when they met a Jassasah." (The narrator said:) I asked (Abu Salamah): What is the Jassasah? He said: "It is a woman (-like creature) who was dragging the hair of her body and her head." She said to those people: In this castle is information about the news you are seeking. So those people went there and found a man tightly bound there. He said: Give me news, or ask me and I will tell you. When the people remained silent, he said: Tell me about the palm groves of Baysan and the spring of Zughar and Amman: have they borne fruit? They said: Yes. Then he asked: Tell me about the muddy spring of Zughar: is there water in it? They replied: Yes, it is full and the water is overflowing its sides. Then he said: He is the Masih (al-Dajjal), for whom the earth will be folded up, and he will travel over the whole face of the earth in forty (days), except Taybah. The Messenger of Allah (peace and blessings be upon him) said: "It (Taybah) is Madinah; at each of its gateways stands an angel holding a sword drawn from its sheath, who will prevent him from entering it, and the same is the case with Makkah." Then he (peace and blessings be upon him) said three times: "He is not in the Sea of Persia, nor is he in the Sea of Rome." Ibn Abi Salamah (may Allah have mercy on him) related that there was also something in this hadith that he did not remember. He said that Sayyiduna Jabir (may Allah be pleased with him) used to testify that the Dajjal is in fact Ibn Sayyad himself. I said: Ibn Sayyad has died. He said: "Even if he has died." I said: He had become a Muslim. He said: "Even if he had become a Muslim." I said: He had entered Madinah. He said: "Even if he had entered Madinah."
