Islamic eschatology is the branch of Islamic scholarship that studies Yawm al-Qiyāmah (Arabic: يوم القيامة, IPA: [jawm.ulqijaːma], "the Day of Resurrection") or Yawm ad-Dīn (يوم الدين, Arabic pronunciation: [jawm ud.diːn], "the Day of Judgment"). This is believed to be the final assessment of humanity by God, 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 at al-Qiyamah. Many verses of the Quran contain the motif of the impending Last Judgment.
Surat al-Qiyama has as its main subject the resurrection. The Great Tribulation is also described in the hadith, and commentaries of the ulama such as al-Ghazali, Ibn Kathir, Ibn Majah, Muhammad 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 twelve major signs. At the time of judgment, terrible corruption and chaos will rule. The Mahdi (prophesied redeemer) will be sent and with the help of Jesus, will battle Masih ad-Dajjal (Antichrist in Islam). They will triumph, liberating Islam from cruelty, and this will be followed by a time of serenity with people living true to religious values. However, there is no mention of the advent of Mahdi and Isa in one era in any of the hadith. Some Muslim scholars translate the Arabic word "Imam" as "Mahdi" to prove the advent of Mahdi and Isa in a single era.
