A hadith in Sahih Bukhari (Sahih al-Bukhari, 4:55:658) says: Very few scholars outside of Orthodox Islam reject all the quotes (Hadith) attributed to Muhammad that mention the second return of Jesus, the Dajjal and Imam Mahdi, believing that they have no Quranic basis. However, Quran emphatically rejects the implication of termination of Jesus' life when he was allegedly crucified. Yusuf Ali's translation reads:  Many classical commentators such as Ibn Kathir, At-Tabari, al-Qurtubi, Suyuti, al-Undlusi (Bahr al-Muhit), Abu al-Fadl al-Alusi (Ruh al-Maani) clearly mention that verse 43:61 of the Quran refers to the descent of Jesus before the Day of Resurrection, indicating that Jesus would be the Sign that the Hour is close. In Ahmadiyya Islam, the present age (the Messianic age) has been a witness to the wrath of God with the occurrence of the World Wars and the frequency of natural disasters. In Ahmadiyya, Ghulam Ahmad (d.1908) is seen as the promised Messiah whose teachings will establish spiritual reform and ultimately establish an age of peace upon earth. This age continues for around a thousand years as per Judeo-Christian prophecies; and is characterised by the assembling of mankind under one faith as per Ahmadiyya belief. In the Baháʼí Faith, the "Messianic Age" refers to a 1000-year period beginning with the Declaration of Baháʼu'lláh in 1863. Baháʼís believe the period of peace and prosperity is gradually unfolding and will culminate in the appearance of "The Most Great Peace".
