高僧傳 9.38

9.38

田融《趙記》云：「澄未亡數年，自營塚壙。」澄既知塚必開，又屍不在中，何容預作？恐融之謬矣。

Tian Rong's Zhao ji states: 'Several years before he died, Fotudeng personally constructed his tomb.' Since Fotudeng already knew that the tomb would certainly be opened and that his corpse would not remain inside, how could he have prepared it beforehand? It is likely an error by Rong.
