Do various Muslim sects disagree about who is a Muslim?

By accepting Mohammed as God's messenger, you are expected to believe in the teaching of Quran, which he recieved as a messenger and to obey him. Rest is between you and God, whether you followed the way shown by him or not.

Hound9_4: Being a Muslim only requires you to believe in 3 things.

1) there is no God but One God

2) Muhammad was his last messanger

3) There is the day of judgement

If yo you believe in these 3 things, you are considered a muslim.

As for other sects believing that other sects are non muslims, i only know of one and thts the one you mentioned.

The Wahhabis consider the Shia non muslims because they havent understood what the shia believe.

it is not like that... as long as you said: no God but ALLAH and Mohammed is his Massenger" then you just become a muslim...

so some muslims have misconception of thier relgion.. and all these misconception are not that value.. cuz after all, ALL muslims read the same holy book Quaran and all pray in the same Mousque...

and about ppl who are not muslims such as christians and Jew: through history they lived between muslims in thier islamic countries in peace.. and no one was beaten to convert to islam.. if you want a proof just see any muslim country and you will always see a percentage of the native relgions in it is pupilation..... except saudia arabia as it is the birthplace of islam and actully there was no real relegion there...

no
