Consider Prophet Jesus' (pbuh) Coming
In almost all works that dwell on the essence of faith of the followers of Sunnah, there is reference to Prophet Jesus' (pbuh) coming to Earth before the Last Day, his struggle against Dajjal and his killing him, and the pervasion of the morality of true religion over the Earth. Assessing the evidence from the Qur'an and the news provided by hadiths altogether, Islamic scholars have adopted faith in Prophet Jesus' (pbuh) return as an important tenet of faith. The related explanations are as follows:
1. In verse 157 of the Surat an-Nisa', God commands, "...They did not kill him and they did not crucify him but it was made to seem so to them...." This verse, together with many others, reveal that Prophet Jesus (pbuh) is alive in God's sight and indicates that he will come to Earth for a second time. Reaching to consensus on this issue, Islamic scholars state that advocating a contrary suggestion is by no means possible. For instance in his commentary of this verse, Ibn Hazm stresses that someone who says Prophet Jesus (pbuh) is murdered would revert back from Islam or become a disbeliever.
2. The fact that the hadiths pertaining to Prophet Jesus' (pbuh) second coming are mutawatir, that is, so clear as to be immune to any doubts, is a great evidence for Muslims. Furthermore, there exists not a single different hadith that maintains otherwise - that is, any hadith that suggests that Prophet Jesus (pbuh) will not return.
3. Another evidence used by Islamic scholars is the hadith narrated by Jabir Ibn Abdullah which says, "Anyone who denies Mahdi's coming has denied what was revealed to Prophet Mohammed (may God bless him and grant him peace). Anyone who rejects Prophet Jesus' (pbuh), son of Maryam, coming has become a disbeliever. Anyone who does not accept Dajjal's appearance has also become a disbeliever."
There is reference to this hadith in very important Islamic resources such as, Fasl al-Khitab by Khwaja Parsa Bukhari, Maani al-Akhbar by Muhammed ibn Ibrahim Kalabadhi, Al-Rawd Al-Unuf by Suhayl, Arf-ul-wardi-fi Akhbar Mahdi by Jalaluddin Suyuti. This aside, Sheikh Abu Bakr has explained the chain of people who narrated this hadith. It is as follows (from the last person to the first): Muhammad Ibn Hasan, Abu Abdullah al-Hussein Ibn Muhammad, Isma'il Ibn Abi Uways, Malik Ibn Abas, Muhammad Ibn Munkadir, Jabir Ibn Abdullah.1
4. The abundance of narrators who reported the hadiths related to Prophet Jesus' (pbuh) coming and their trustworthiness is another issue to which Islamic scholars draw attention. Some of the narrators who reported these hadiths are: Abu'l Asas as-Sanani, Abu Rafi, Abul Aliyya, Abu Umama al-Bahili, Abu'd Darda', Abu Hurayra, Abu Malik al-Hudri, Jabir Ibn Abdullah, Hudhayfa Ibn Adis, Safina, Abu Qatada, Uthman Ibnul 'Aas, Nafi' Ibn Kaysani, Al Walid Ibn Muslim, Ammar Ibn Yathir, Abdullah Ibni Abbas...
As a result of all this information, Islamic scholars have considered faith in Prophet Jesus' (pbuh) return to Earth and the pervasion of the morality of the true religion as an important essence of faith.
