time machine actually got invented,and we bring back muhammad and jesus to the future and they say 'i made the religion shit up,actually there's no allah no god,can't believe you guys still believe in it after hundreds of years lol'
what would happen?
Well your sort of right lol.
Mohammeds message is finished, he wont come back.
Jesus will come back, we will wait for him to come and see what he says..
