Khasf al-Bayda

According to hadiths, there are five (or more) certain signs which will happen prior to the reappearance of the twelfth (last) Imam of Shia Islam, al-Mahdi.[12][13] Al-Shaykh al-Saduq has narrated --from Ja'far al-Sadiq-- that: five signs are decisive before the rising of Qa'im (قائم): Yamani, Sufyani, Heavenly cry (calling) from the sky, The murder of Nafs-e-Zakiyyah and Khasf al-Bayda.[14][15]

Sufyani and his army will go toward Iraq to attack the Mahdi. When the army enters the territory of Bayda, the Earth will consume the army of Sufyani except for 2 or 3 individuals.[16] Various hadiths discuss the numbers in the army of Sufyani.[17][18][19][20] Some sources say that the army of Sufyani will number 12,000;[21][22] while some say 170,000[23][24] and other sources say 300,000[25]

According to a tradition from Muhammad al-Baqir: at the End Time, when Sufyani's army enters the territory of Bayda, a voice will call out:

"O plain, annihilate the nation" (i.e. the army of Sufyani)
