Hurr Al Amili explains what Kulayni meant by ,,Sahih”

Sheikh Hurr Al Amili writes:

“Know, that whatever Al-Kulaini narrates, does not belittle his status in any way and although he mentioned at the beginning of his book that his narrations are authentic (Sahih), he meant the affirmation of their contents by additional evidences and the affirmation that the contents have been narrated by the Infallible, but not that it must be acted upon according to its outward appearance if there is something that contradicts it.”
