Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Hudhaifah (may Allah be pleased with him) that he said: A beast will emerge twice before the Day of Judgment, to the extent that at the time of its emergence, men will be killed. Then it will emerge a third time and will come to the people of the largest mosque among your mosques, at a time when they will be gathered around one man. Then the beast will say: Who has gathered you with the enemy of Allah? The people will hurry, and the beast will mark the disbeliever, to the extent that when two men engage in a transaction, one will say, "Take it, O believer," and the other will say, "Take it, O disbeliever."
