Many Muslims forget what is the role of a Prophet. Yes, he brought us Islam, codified our law, and relayed us the Quran, but one of the main roles of a prophet is to prophesize about the future.
A few things which must happen in yawm ul akhir (Last Day):
1. Coming of al masih ad dajjal (Anti-Christ) and rule from Israel typified by oppression
2. Beast of the Earth (dabbat ul ardh) dividing the world into Kaffir and Muslim
3. genocide of the Arabs, fighting over Iraq's newly uncovered wealth
4. Conquest of Hind by Khorasaan black flag army
5. emergence of the Mahdi in Madina and establishment of the Mahdi state
6. Khorasaan army joining Imam Mahdi
7. re-emergence of ISA a.s./Jesus in the Holy Land
8. Defeat of masih ad Dajjal by Isa a.s.
4. emergence of Gog and Magog (Yajuj and Majuj), much genocide and bloodshed, eventual defeat via parasites due to Isa a.s. dua
8. Rule of the world by Isa a.s. from newly liberated Jerusalem
9. Some years of peace
10. Cold wind which wipes out believers only
11. destruction of the Earth on the worst of humanity
12. Judgement Day (Yawm ul Qiyamat)
Not all are necessarily in this order. Hadith are Saheeh or Hasan.
