3:144 Remember that Muhammad is only a Messenger. The messengers before him have passed on. So, if he died or were slain, would you turn about on your heels? But anyone who turns about his heels, would not, in the least, harm God. And God will soon reward those who remain appreciative (for the Guidance).
[The System the Messenger has established is to become a Beacon of Light for all humanity. The believers will reap the fruit of the Benevolent System here and then, get rewarded in the Hereafter. 3:101, 3:185, 35:10]
All Messengers before Muhammad are dead, so how could Jesus, a messenger of Allah, be raised up alive to heaven and remain alive when Allah had said he is dead?
You can make Bukhari your lord and master, believe every word he wrote about the Last Messenger, you have that choice to do so, but I prefer Allah.
