(31) Ahmad bin Muhammad bin Sa’eed narrated that Hisham bin Salim had said: I heard Abu Abdullah as-Sadiq saying: “There will be two cries; one at the beginning of night and the other will be at the end of the second night.” I asked: “How will that be?” He said: “One will be from the Heaven and the other will be from Iblis.” I said: “How one will be distinguished from the other?” He said: “He, who has known about them before they occur, will know which of them is from the Heaven.”
