Have not tested this out but this should work:

location / {
if (!-e $request_filename){
rewrite ^/([a-zA-Z0-9_]+)$ /$1.php last;
}
}

location /profile {
rewrite ^/profile/([a-zA-Z0-9._@-]+)$ /profile.php?u=$1 last;
rewrite ^/profile/ /profile.php last;
}

location /groups {
rewrite ^/groups/([0-9]+)$ /groups.php?grp=$1 last;
rewrite ^/groups/ /groups.php last;
}

location /view_post {
rewrite ^/view_post/([a-zA-Z0-9]+)$ /view_post.php?post=$1 last;
}

error_page 404 /Faiyaz/Instagram/404.php;

deny all;

location ~ .php$ {
