These shias quote tareekh books for example Tabari.
They take only things written against Sahabah.
Sunnis know what is written against Ali in the same books but of respect we don't say it.
We know that history books have all kind of information.
These bad people called Shia take advantage of that.
So now I will show you only one glimpse what Tabari has written about Ali.
It says long as Fatima was alive ( 6 months), Ali had lots of sympathy and favour from muslims. So he did not do bayat of Abu Bakr for 6 months. Tell me, is it the character of Imam-=e-Masoom. ( I love Hz Ali but just to show you how bad these shias beliefs are, I just showed you one example.)
After Fatima wisal death, Ali's importance was also gone. When Ali realized that, his attitude changed and he did bayat of Abu Bakr.
Then about property of Prophet (SAWW), Hz Abu Bakr did not give to Fatima and Ali but every month he gave them money.
