What did Prophet Muhammad (saw) say about the time between the two blowing of the trumpet?
 Narrated Abu Huraira:                     The Prophet said, "Between the two blowing of the trumpet there will be forty." The people said, "O Abu Huraira! Forty days?" I refused to reply. They said, "Forty years?" I refused to reply and added: Everything of the human body will decay except the coccyx bone (of the tail) and from that bone Allah will reconstruct the whole body.
