Obvioulsy you need to be a catholic and have all the means of salvation completed to go to heaven. Its siple here is a contradiction in the Quran:
Hey , I have a CONTRIDICTION for you to look t for me:
Will jesus burn in hell? Jesus is raised to Allah, [sura 4:158] near stationed with him [sura 3:45] worshiped by billions of christians yet Sura 21:98 says, that all who worshiped by men other then allah will burn in the eternal flame with all who worship them. CONTRIDICTION- jesus cant be in heaven and hell forever at the same time!
Also, the bible was written 500 years before the quran and we know from new data that it was never changed, only if the apostles wrote it diffrently then they were supposed to, but we know that didnt happen beacue god made them inflamible.
The virgin mary, wich it cenerated by catholics as much a muslims, is continulsly going around the world, appearing ontop of churches bowing to the cross, and while many msulims go there to see such things they go there and pray on "prayer rugs" to this site. How can this be? If the virgin marys is bowing to a cross? It seams that would contridict all of muslims.
There are 73 sects of islam "and while one man can create one faith and achive a billion to fallow, an other will make 73 and achive less." There are over one billion catholics, and 2 billion christains. While only 13 millions people have to follow each sect to make up the amount of people thta follow islam.
Also each gruop of islam contridicts the other, like how only some belive that jesus was a prophet.
Also if you want to go here its awesome!
