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 AbuSalamah: 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.
