Mustadrak al-Hakim — Hadith 8702

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: "The people will be travelling by night towards Jam' (Muzdalifah), and the Beast of the Earth (Dabbat al-Ard, the creature that will come out of the earth) will be advancing towards them. By morning it will have encircled them all between its head and its tail. There will be no believer except that it wipes him (and marks him), and no hypocrite or disbeliever except that it brands him on the nose. Up to that time the door of repentance will be open. Then the smoke will appear, which will afflict the believer with something like a cold, while it will enter the ear openings of the disbeliever and the hypocrite until they become (swollen) like roasted meat. Even then repentance will be accepted, until the sun rises from the west."
This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.
