The Messenger of Allah (ﷺ) once delayed the congregational night prayer.

He came out and said: The talk of Tamim ad-Dari detained me. He transmitted it to me from a man who was on of of the islands of the sea. All of a sudden he found a woman who was trailing her hair. He asked: Who are you?

She said: I am the Jassasah. Go to that castle. So I came to it and found a man who was trailing his hair, chained in iron collars, and leaping between Heaven and Earth.

I asked: Who are you? He replied: I am the Dajjal (Antichrist). Has the Prophet of the unlettered people come forth now? I replied: Yes. He said: Have they obeyed him or disobeyed him? I said: No, they have obeyed him. He said: That is better for them.
