Errors in the Words of Prayer and the Ruling on the Prostration for Forgetfulness
Machine translationRead the Arabic original
The questioner:
This questioner, Ali, says: Shaykh, if one makes a mistake in the prayer, for example, saying "Allahu Akbar" instead of "Sami' Allahu li man hamidah," or saying "Sami' Allahu li man hamidah" instead of "As-salamu alaykum," what is required of him in this case?
The Shaykh:
In this case, he is required to perform the prostration for forgetfulness, because the takbirs other than the takbir of ihram are an obligatory part of the prayer, and whoever leaves an obligatory part, it becomes obligatory for him. As for leaving the salam, if he does not perform it, and if he leaves the salam and says a different phrase due to forgetfulness or negligence, he should perform the salam, and he owes nothing. He performs the prostration for forgetfulness regarding the phrase he said. So, he performs the prostration for forgetfulness, but he must perform the salam because it is a pillar.
The presenter:
May Allah reward you with good, this questioner.
The Shaykh:
If the time passes and he has not performed the salam, he must repeat the entire prayer. Yes.
The presenter:
May Allah reward you.
