(i) Narrated Abu Huraira:
Allah’s Apostle said, "By Him in Whose Hands my soul is, son of Mary (Jesus) will shortly descend amongst you people (Muslims) as a just ruler and will break the Cross and kill the pig and abolish the Jizya (a tax taken from the non-Muslims, who are in the protection, of the Muslim government). Then there will be abundance of money and no-body will accept charitable gifts."
Sahih al-Bukhari, Volume 3, Book 34, Number 425
(ii) Jabir b. 'Abdullah reported: I heard the Messenger of Allah (may peace be upon him) say: A section of my people will not cease fighting for the Truth and will prevail till the Day of Resurrection. He said: Jesus son of Mary would then descend and their (Muslims') commander would invite him to come and lead them in prayer, but he would say: No, some amongst you are commanders over some (amongst you). This is the honour from Allah for this Ummah.

(i) Narrated Abu Huraira:
The Prophet said, "The Israelis used to be ruled and guided by prophets: Whenever a prophet died, another would take over his place. There will be no prophet after me, but there will be Caliphs who will increase in number." The people asked, "O Allah's Apostle! What do you order us (to do)?" He said, "Obey the one who will be given the pledge of allegiance first. Fulfil their (i.e. the Caliphs) rights, for Allah will ask them about (any shortcoming) in ruling those Allah has put under their guardianship."
Sahih al-Bukhari, Volume 4, Book 56, Number 661.
(ii) Narrated Jubair bin Mutim: Allah's Apostle said, "I have five names: I am Muhammad and Ahmad; I am Al-Mahi through whom Allah will eliminate infidelity; I am Al-Hashir who will be the first to be resurrected, the people being resurrected there after; and I am also Al-'Aqib (i.e. There will be no prophet after me)."
