The questioner:
Honorable Shaykh, may Allah grant you success, he says: If the imam forgot a pillar in his prayer and did not remember it until the fourth rak'ah, so he stood for a fifth instead of the fourth, what does the ma'mum do? Does he follow him?
The Shaykh:
Until when?
The questioner:
The imam forgot a pillar in his prayer and did not remember it until the fourth rak'ah, so he stood for a fifth instead of the fourth. He says: What does the ma'mum do? Does he follow him?
The Shaykh:
If the ma'mum knows that it is an extra rak'ah, it is not permissible for him to follow. Here, he did not know that it was extra, so he follows the imam. Yes.
