Mohammed cursed Christians on his deathbed

 

Volume 2, Book 23, Number 472:

Narrated 'Aisha:

Allah's Apostle in his fatal illness said, "Allah cursed the Jews and the Christians, for they built the places of worship at the graves of their prophets."

From Avenging Apostate:

Compare that with what Christ said. And also consider this: Today, his own followers take pains to go to Medina, where he’s buried, to just look at his grave and be able to touch the golden bars (prison!) that are there to stop people from entering the grave area and touching the grave itself.
