According to the Hadith of Abu Sarihah, Hudhayfah bin Asid Al-Ghifari, may Allah be pleased with him, said,

"The Messenger of Allah looked out upon us from a room while we were discussing the Hour. He said:

لَاا تَقُومُ السَّاعَةُ حَتْى تَرَوْا عَشْرَ ايَاتٍ طُلُوعَ الشَّمْسِ مِنْ مَغْرِبِهَا وَالدُّخَانَ وَالدَّابَّةَ وَخُرُوجَ يَأْجُوجَ وَمَأْجُوجَ وَخُرُوجَ عِيْسَى ابْنِ مَرْيَمَ وَالدَّجَّالَ وَثَلَاثَةَ خُسُوفٍ خَسْفٌ بِالْمَشْرِقِ وَخَسْفٌ بِالْمَغْرِبِ وَخَسْفٌ بِجَزِيرَةِ الْعَرَبِ وَنَارًا تَخْرُجُ مِنْ قَعْرِ عَدَنَ تَسُوقُ النَّاسَ أَوْ تَحْشُرُ النَّاسَ تَبِيتُ مَعَهُمْ حَيْثُ بَاتُوا وَتَقِيلُ مَعَهُمْ حَيْثُ قَالُوا

The Hour will not come until you see ten signs.

The rising of the sun from the west;

the smoke;

the beast;

the emergence of Ya'juj and Ma'juj;

the appearance of `Isa bin Maryam;

the Dajjal;

three cases of the earth collapsing -- one in the east, one in the west, and one in the Arabian Peninsula;

and a fire which will emerge from the bottom of Aden and will drive the people -- or gather the people -- stopping with them when they stop to sleep at night or rest during the day."
