Musannaf Ibn Abi Shaybah 37873 — Mutarrif bin al-Shikhkhir

It is narrated from Mutarrif, who said: I saw in a dream as though I had gone out intending to attend Friday prayer. I came to the graveyard of the neighbourhood and saw that the people of the graves were sitting. I wanted to greet them and pass on, but they said: "O Abdullah, where are you heading?" I said: "I am heading for Friday prayer." Mutarrif said: Then I asked: "Do you know what Friday is?" They said: "Yes, and we also know what the birds say on that day." Mutarrif said: I asked: "What do the birds say on that day?" They said: "The birds say: Peace, peace, a good day."
