How to join tables in mysql
===

I have two tables as below:

    users
     -id (primary key, AUTO_INCREMENT)
     -username (varchar)
     -password (varchar)

    users_messages
     -id (primary key, AUTO_INCREMENT)
     -message (text)
     -fk sender_id (int)
     -fk receiver_id(int) 
     -sent_date(datetime)
     -is_read(tinyint)

Both foreign keys in users_messages references same table i.e users
I want to write a sql query to get output as below:

    Message                Sender            Receiver
    Message 1 testing      john              sonam
    Message 2 testing      meena             shenaz

How can i do this? I need to fetch all the messages from users_messages table with sender_id and receiver_id replaced by username column in users table
