Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "I was asleep when the treasures of the earth were brought to me, and two gold bangles were placed in my hands. They were burdensome for me and caused me distress and anxiety. It was revealed to me to blow on them, so I blew, and both (were removed) from my hands. I interpreted this dream to mean that they represent two liars between whom I am (i.e., who will appear in my time): (1) the master of Sana'a (i.e., Aswad Ansi) and (2) the master of Yamamah (i.e., Musaylimah the liar)."

Sayyiduna Hudhayfah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "There will be twenty-seven extremely great liars and impostors in my Ummah, four of whom will be women. (Remember that) I am the Seal of the Prophets; there will be no prophet after me."

A man from Kufa was sitting with Sayyiduna Abdullah bin Umar (may Allah be pleased with them). He began narrating ahadith from Mukhtar. Sayyiduna Abdullah said: If the matter is as you are saying, then I heard the Messenger of Allah (peace and blessings be upon him) say: "Before the Day of Judgment, there will be thirty extremely great liars and deceivers."
