It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said:“When three signs (of the Day of Judgment) appear, then «لَا يَنْفَعُ نَفْسًا إِيمَانُهَا لَمْ تَكُنْ آمَنَتْ مِنْ قَبْلُ أَوْ كَسَبَتْ فِي إِيمَانِهَا خَيْرًا» (6-al-An’am:158) the faith of a person will not benefit him who had not believed before, or who had not earned any good through his faith.”(Those three signs are:) the rising of the sun from the west, the Dajjal, and the Beast of the earth.”

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A beast will emerge, it will put a mark on the people's noses, and they will live long lives, to the extent that a man will buy a camel. When another person asks him, 'From whom did you buy this camel?' he will reply, 'I bought it from one of the marked people.'"
