Before we discuss Islam's attitude regarding the concept of classes it may be useful to try to understand what is generally meant by a "class system". In medieval Europe, for instance, there were three distinct classes: the nobility, the clergy and the common people.
The clergy had their own distinctive clothes. In those ages the power of the church was equal and at times opposed to that of kings and emperors. The Pope claimed that it was he who conferÂred power on kings but they strove to get rid of his influence in order to rule independently. Owing to the property donated by the religious people and the exactions imposed on them, the church became so rich that at times it could have armies of its own. On the other hand, the nobility inherited nobleness from their forefathers and passed it on to their descendants. A man belonged to the nobility by birth and remained as such until his death regardless of whatever noble or mean actions he might have done in his lifetime.
