You said that if speech occurs from someone who is unaware, his prayer is not invalidated, and that if someone slaughters without mentioning the name of Allah while unaware, his slaughter is not lawful. What is the difference?

The questioner : Shaykh, we said that the one who speaks during prayer while unaware is not subject to a specific ruling.
The Shaykh : Yes.
The questioner : And regarding the timing of mentioning the name in slaughter, we said that the slaughter of the two she-camels is valid, and the verse is interpreted as referring to sin. Why did we not interpret it here as referring to sin, such that his prayer is invalidated like the slaughter?
The Shaykh : Yes. Who will answer this question?
The questioner : I did not hear you, Shaykh. I was not paying attention.
The Shaykh : He says: You stated that if speech occurs from someone who is unaware, his prayer is not cut off due to the generality of His saying:[Al-Baqarah 2:286] And you stated that if someone slaughters without mentioning the name while unaware, his slaughter is not lawful, and you did not say that the verse is general, but rather you interpreted it as negating accountability for sin.
The student : There is a difference between committing a prohibited act and leaving off an obligatory act. Leaving off an obligatory act is not known,
The Shaykh : Yes.
The student : More than once.
The Shaykh : Correct. This is how the scholars distinguished. They said there is a difference between an act that invalidates the worship and an act whose omission invalidates the worship. The latter falls under the category of performing what is commanded, so it is necessary. If a person leaves it off while unaware, the sin is dropped from him, and the ruling of the act applies to him, unlike the prohibited act. Yes.
The Shaykh : Yes.
