本經與巴利經典增支部第10集55經的內容完全相同，是由智慧第一的舍利弗尊者對其他比丘所說的法。
本經的標題「無」一字是指「退失善法」之意，就像我們從小聽過的ㄧ段話:學如逆水行舟，不進則退。如果修行人的態度放逸，不積極聞法，也不依法奉行，到頭來過去的修行都將落空。

我是這樣聽聞的：
有一次，佛陀遊方到了古印度的舍衛國，並暫時住在勝林給孤獨園林裡。
當時，尊者舍利弗尊者對諸比丘開示：「諸位賢者！如果有比丘、比丘尼沒有聽聞過的法不去聽聞，或將曾聽過的法給忘掉了。那麼就算他(她)過去有修行，也曾廣讀經文並加誦習，對法也有所領悟，但最後一切的努力都將落空及失去。他(她)會逐漸的把過去所學到的都給忘失；他(她)過去本來通曉的法義也會變成無知。
以上就是所謂的：比丘、比丘尼淨法衰退。
諸位賢者！如果有比丘、比丘尼對沒有聽聞過的法能恭敬地去聽聞，或將已經聽過的法給牢記在心。那麼他(她)過去的修行、曾廣讀過的經文、對法義的領悟等功德，都不會失去。他(她)絕對不會把過去所學到的法給忘掉；他(她)會對過去所學到的法愈來愈清楚，也愈來愈有心得。
以上就是所謂的：比丘、比丘尼淨法轉增。
諸位賢者！比丘在平時都應當作以下如是觀來檢視自己：『我的心中有沒有貪婪？有沒有瞋恚心？有沒有昏沉睡眠纏？有沒有掉舉?有沒有驕慢貢高？我對法有沒有疑惑？我的生理狀況是否有躁動不安的現象？我有沒有穢污心？我有沒有信心？我有沒有精進？我有沒有正念？我有沒有正定？我有沒有邪見？』
若比丘發現自己有以上的惡不善法，想要滅除，便應當趕緊尋找正確的方法，精勤修行，保持正念、正智，安住於善法，不要令其退失。
就好比有人的身上著火，火都燒到他的頭髮及衣服，他應該趕緊找正確的救火方法滅火。
若比丘發現自己並沒有以上的惡不善法，如果比丘想要保持住善法，不忘不退，修行廣布，也應當趕緊尋找正確的方法，精勤修行，保持正念、正智，安住於善法，不要令其退失。
就好比有人的身上著火，火都燒到他的頭髮及衣服，他應該趕緊找正確的救火方法滅火。」
當尊者舍利弗所說完後，諸比丘聽聞尊者舍利弗所說的開示，都心生歡喜，並依法奉行。

我聞如是： 一時，佛遊舍衛國，在勝林給孤獨園。 爾時，尊者舍梨子告諸比丘： 「諸賢！若有比丘、比丘尼未聞法者不得聞，已聞法者便忘失，若使有法本所修行、廣布誦習、慧之所解，彼不復憶，知而不知。諸賢！是謂：比丘、比丘尼淨法衰退。 諸賢！若有比丘、比丘尼未聞法者便得聞，已聞法者不忘失，若使有法本所修行、廣布誦習、慧之所解，彼常憶念，知而復知，是謂：比丘、比丘尼淨法轉增。 諸賢！比丘者，當作如是觀：『我為有增伺？為無有增伺？我為有瞋恚心？為無有瞋恚心？我為有睡眠纏？為無有睡眠纏？我為有{調}[掉]貢高？為無有{調}[掉]貢高？我為有疑惑？為無有疑惑？我為有身諍？為無有身諍？我為有穢污心？為無有穢污心？我為有信？為無有信？我為有進？為無有進？我為有念？為無有念？我為有定？為無有定？我為有惡慧？為無有惡慧？』 諸賢！若比丘觀時，則知：『我有增伺、有瞋恚心、有睡眠纏、有{調}[掉]貢高、有疑惑、有身諍、有穢污心，無信、無進、無念、無定有惡慧。』者，諸賢！彼比丘欲滅此惡不善法故，便以速求方便，學極精勤，正念、正智，忍不令退。諸賢！猶人為火燒頭、燒衣，急求方便救頭、救衣。諸賢！如是，比丘欲滅此惡不善法故，便以速求方便，學極精勤，正念、正智，忍不令退。 諸賢！若比丘觀時，則知：『我無增伺、無瞋恚心、無睡眠纏、無{調}[掉]貢高、無有疑惑、無有身諍、無穢污心，有信、有進、有念、有定、無惡慧。』者，彼比丘欲住此善法，不忘不退，修行廣布故，便以速求方便，學極精勤，正念、正智，忍不令退。猶人為火燒頭、燒衣，急求方便救頭、救衣。諸賢！如是，比丘欲住此善法，不忘不退，修行廣布故，便以速求方便，學極精勤，正念、正智，忍不令退。」 尊者舍梨子所說如是，彼諸比丘聞尊者舍梨子所說，歡喜奉行。
