I was just reading tahdhib ahwal al-qubur by Ibn Rajab al-Hanbali and the Salafi editor just stated dead normal that he removed some stories of the Tabi'in, and some narrations about gravediggers, simply because they had 'no proof' according to him. http://www.waqfeya.com/book.php?bid=1155 (p. 6) If only if they had let the reader decide!
