The Ruling on the Invocation at the Time of Slaughter and Its Excuse in Case of Forgetfulness

Question:
I ask for a detailed explanation regarding the invocation at the time of slaughter: is it a condition or an obligation? And if it is a condition, is it excused in case of forgetfulness? And is it permissible...

Answer:
The invocation over the slaughtered animal is a condition for the validity of the lawful slaughter; it is a condition for the validity of the lawful slaughter. And if one forgets it, it is excused by the forgetfulness, because he did not intentionally leave off the invocation, so the slaughtered animal is lawful and he is excused for the forgetfulness. Yes.
