How is Papal Infallibility different from Ismah?

So one of the things us Catholics use as a source to show we are the one true faith is the concept of Papal Infallibility and the infallibility of the Magesterium.

Islam has a similar concept though called Ismah

Obviously these are two contrasting religions so one of them is not infallible…so how do we decide?

What are the differences between the two?

Which religion was founded by someone who claimed to be God, foretold his own death and resurrection and then backed it up by rising from the dead?

At least, that’s where I might start. :wink:
