Silsilah Sahihah

A man from Kufa was sitting with Sayyiduna Abdullah bin Umar (may Allah be pleased with them), and 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 Hour, there will be thirty extremely great liars and impostors.'"
