Then, the hadith should have been ’ how will people of latter time’s condition be when Jesus a.s will descend among THEM, and THEIR imam will be from among THEM "
Talking to sahabah , and yet u take it as people of latter times. Then taking Jesus a.s to be the same person. Makes no sense. Do you agree that latter people is called ‘sahaba’ metaphorically like that of Muhammad PBUH’s sahabah ?
YOUR condition. YOUR Imam, from among YOU. Rather than ‘their’ condition, ‘their’ imam, from among ‘them’.
Also, is our imam not always from among us ?? and where does it say its Imam mahdi ?
‘son of Mary’ is a quality. All momineen are referred by Allah by Mariam Bibi (as) and Asiya bibi. Whosoever keeps themselves unchaste is like that of Mariam (as). Isa a.s is the name given by Muhammad PBUH to the future person so that people realize his role will be that of Isa a.s. Just like how Isa a.s came at the end of Musvi shariya.
Jesus a.s is dead. Hes not coming back. People who die do not come back to life until the day of judgement. Also, previous prophets do not come in the future prophet’s shariyah. This is not acceptable by the teachings of Islam. Jesus a.s despite being a prophet of Allah and preacher of tawheed is NOT muslim as the muslim shariyah came into existence AFTER the appearance of holy prophet pbuh.
