How to prevent a bot from pinging people with @everyone?

Question

Python

I need that when a person writes the say command, the bot could not ping everyone
For example:
Human: !say @everyone hello
Bot: @everyone hello(pings everyone)
How can I remove the ability to ping everyone by the bot?

@bot.command()
async def say(ctx, *arg):
    await ctx.message.delete()
    author = ctx.message.author
    msg = ctx.message.content
    print(author, msg)
    await ctx.send(' '.join(arg))

Add check for ping text. If it's equal to @everyone - don't execute the function. If it's not equal, do it. Or you can check if the message does not contain @everyone
