I know speaking of Islam without knowlege is forbidden. But what about speaking without knowledge not involved with Islam?
Example: Many non Muslims write their own biased and personal definitions of people's names, type of people and other words in urbandictionary.com . Most of these words are sexist and made mostly by non Muslim Americans.
Another question, is being biased a sin? Lets say if you hate a group of people by one person and you give judgment, think, and act by your personal feelings?
Thanks.
