The follower’s following the imam in an extra rak'ah
Machine translationRead the Arabic original
The questioner:
Honorable Shaykh, may Allah grant you success. If the imam forgets in the prayer and adds a rak'ah, and the follower follows him while being certain that he added it, is the follower’s prayer valid, or does he have to repeat his prayer?
The Shaykh:
If he considers the ruling and knows that it is an extra rak'ah, but he is unaware of the legal ruling, his prayer is valid. However, if he knows that it is an extra rak'ah and knows the legal ruling that it is not permissible to follow him in it, then his prayer is invalid because he intentionally added to it.
The presenter:
Or.
The Shaykh:
They say: And the prayer of the one who followed him knowingly is invalid, not the one who did so out of ignorance or compulsion.
