Introduction To Islamic Eschatology By Sheikh Imran Hosein

Islamic Eschatology is the branch of Islamic scholarship that studies Yawm al-Qiyāmah (pronounced yome-ul-key-ah-mah; Arabic: يوم القيامة‎ "the Day of Resurrection") or Yawm ad-Dīn (pronounced yome-ud-dean; يوم الدين "the Day of Judgment"). This is believed to be the final assessment of humanity by Allah, consisting of the annihilation of all life, resurrection and judgment.
The time of the event is not specified, although there are major and minor signs which have been foretold to happen with Qiyamah at the end of time. Many verses of Qur'anic Sura contain the motif of the impending Day of Resurrection.
The 75th Sura of the Qur'an, "al-Qiyama", has as its main subject the resurrection. Its tribulation is also described in the hadith, and commentaries of Islamic expositors such as al-Ghazali, Ibn Kathir, Ibn Majah, al-Bukhari, and Ibn Khuzaymah.The Day of Judgment is also known as the Day of Reckoning, the Last Day and al-sā'ah, or the Hour.
The hadith describe the end time with more specificity than the Qur'an, describing the events of al-Qiyamah through 10 major signs. At the time of judgment, terrible corruption and chaos will rule. The Mahdi will be sent and with the help of Isa, will battle Masih ad-Dajjal. They will triumph, liberating Islam from cruelty, and this will be followed by a time of serenity with people living true to religious values.
