On the Imam’s Forgetfulness: Why Does the Imam Not Act on a Single Report?

The questioner : Shaykh, we stated here that it is permissible to accept a report from a single narrator, and this is established in this hadith. However, regarding the prostration for forgetfulness, we said that if only one person reminds him, he is not obligated to follow that person’s statement, which is a report. We said that two people must remind him. Here, we said that in religious matters, it is permissible to accept a report from a single narrator. So why did we not accept it?

The Shaykh : Yes, that is right. Two people must remind him if he has something that contradicts the single reminder.
As for when only one person reminds him and he has nothing to contradict it, then he should follow that person. Yes.
