Serfs may eventually work their way to freedom (usually not), if you know the term tenant farmers, individuals who work on a property with some believe that eventually they may pay their debts off and become a freeman. An enslaved person, will never believe that they will eventually become free.
-My opinion anyway (probably wrong) but worth a try.
There are two different types of muslims: the sunni muslims and the shiite muslims. the source of conflict that these two muslim groups disagree on is the prophet muhammad’s sucession. the shiites believe that the prophet muhammad should have been succeeded by his son-in-law, while the sunnis believe that the leadership of the muslims should be passed down via hereditary succession.
hope this helps! :)
