Chapter 39: Battles (Kitab Al-Malahim)
Narrated Jabir ibn Abdullah: The Messenger of Allah (ﷺ) said one day from the pulpit: When some people were sailing in the sea, their food was finished. An island appeared to them. They went out seeking bread. They were met by the Jassasah (the Antichrist' s spy). I said to Abu Salamah: What is the Jassasah? He replied: A woman trailing the hair of her skin and of her head. She said: In this castle. He then narrated the rest of the (No. 4311) tradition. He asked about the palm-trees of Baysan and the spring of Zughar. He said: He is the Antichrist. Ibn Salamah said to me: There is something more in this tradition, which I could not remember. He said: Jabir testified that it was he who was Ibn Sayyad. I said: He died. He said: Let him die. I said: He accepted Islam. He said: Let him accept Islam. I said: He entered Medina. He said: Let him enter Medina.
