Silsilat al-Ahadith al-Sahihah

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.”
