Hullo, anon,

I reverted your edits on Mu'awiya I because all the points you raised were covered later. The first paragraph is just an introduction  the rest of the article explains everything in the introduction in much more detail. Also, English seems to be a second language for you and your English is sub-standard. Finally, it is NOT OK to use honorifics like Hazrat, or SA, or PBUH, etc., because this is an encyclopedia for everyone. Non-Muslims use it too, and we should not use language that assumes that readers are Muslims. 

This was not the best first edit ever, but people have gone on from stuff worse than this to become good editors. You might also consider editing the Wikipedia in your first language, whatever it is.
