Answer 1

add_filter( 'the_content', 'filter_the_content_in_the_main_loop' );

function filter_the_content_in_the_main_loop( $content ) {

    // Check if we're inside the main loop in a single post page.
    if ( is_single() && in_the_loop() && is_main_query() ) {

       return esc_html__("So Friends, How is our Article of ".get_the_title().". Do You Like it? Don't Forget to Comment below if Any Queries. For More Article regarding ".get_the_title()." Subscribe Us.").$content;
    }

    return $content;
}
