Khasf - e - Byda

"Khasf –e- Byda" which the multiplicity and variety of resources about it is a sign of its importance and attemts of the early writers, is certain signs of emergence of Imam Mehdi that Shiite authentic communities have reported its related Hadith and also reliable Sunni sources have also discussed about it. Its amplitude is drawn to the jurisprudential debates. The meaning of "Khsf Byda" lies in the fact that Sufiani troops moved with intention of the killing of Imam Mahdi from Mecca to Medina but in the middle of the road they went down into the earth in the land of Byda miraculously. The miraculous realisation of this event shows that the will of God supersedes to save Mahdi as the last messiah even with the intervention of supernatural forces.
