The questioner : The hadith regarding acting upon a hadith that Hafiz Ibn Kafar authenticated conditionally, meaning he made it conditional, saying, “If so-and-so’s hearing from so-and-so is authentic, then the hadith is authentic and one acts upon it,” O Shaykh?
The Shaykh : No, one does not act upon it unless the condition is fulfilled. However, regarding the phrase “one acts upon it,” if you mean that one rules on its authenticity, then no. But if you mean that one acts upon it because of other corroborating narrations that indicate its authenticity, then yes.
The questioner : Yes, I mean acting upon it because of its authenticity. Yes.
The Shaykh : No, no, one does not act upon it.
