Property [body] does not exist on this collection instance

I get this error when I try to fetch data from my database based on slug

This is my controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;

class BlogController extends Controller
{
    public function getSingle($slug) {
        // Fetch from the DB based on slug
        $post =  Post::where('slug', '=', $slug)->get();

        // Return the view and pass in the post object
        return view('blog.single')->with('post', $post);
    }
}

And this is my single.blade.php

@extends('main')

@section('title', '| ')

@section('content')

    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <h1>hi</h1>
            <p></p>
        </div>
    </div>

@endsection

My database has only one row of data and it has the slug named(slug)
