Is the suspicion of impurity a fortiori?

The questioner : Certainly, the Prophet (peace and blessings be upon him) on the day of the matter that reaches three, if we are Shaykh 'Adnan regarding impurity, meaning they said this is from impurity, is it not the case that the analogy in impurity is a fortiori? Truly? Either he says it is an act of worship or he is bound by this, meaning if the suspicion with the Shaykh reaches three, then it may be impurity.

The Shaykh : So the certainty is a fortiori. We said this, we did not say that, but who said that the suspicion of impurity?

The questioner : Because we did not find it.

The Shaykh : Who said this? Because if you put your hand in a sack, did you understand? And you tied it up, you are certain that no impurity touched it.

The questioner : Yes, let's go out.

The Shaykh : It is not an act of worship, but this resembles the saying of the Messenger (peace and blessings be upon him) So these hands, perhaps Satan has an action in them, an action that is harmful to the person even if it is not impure, yes.
