What does the ma'mum do if his imam adds a rak'ah?
Machine translationRead the Arabic original
The questioner : What is your ruling if the masbuq is one rak'ah behind in the congregational prayer? Then his imam finishes and adds a rak'ah, so what does the ma'mum do?
The Shaykh : He follows him, then he performs the rak'ah that he missed. The rak'ah that the imam added is a rak'ah of forgetfulness that has no value, and therefore the Lawgiver did not make the prostration for forgetfulness obligatory.
The questioner : Should I rephrase the question, O Shaykh?
The Shaykh : You do not rephrase the question unless you did not understand the answer, in which case I will repeat the answer. Did you understand the answer? And this is sufficient, and praise be to Allah, Lord of the worlds.Sunan Abi Dawud 4859Hasan Sahih (Al-Albani)
The Shaykh : He follows him, then he performs the rak'ah that he missed. The rak'ah that the imam added is a rak'ah of forgetfulness that has no value, and therefore the Lawgiver did not make the prostration for forgetfulness obligatory.

The Shaykh : You do not rephrase the question unless you did not understand the answer, in which case I will repeat the answer. Did you understand the answer? And this is sufficient, and praise be to Allah, Lord of the worlds.
Glory be to Thee. O Allah, and I begin with praise of Thee, I testify that there is no god but Thou; I ask Thy pardon, and return to Thee in repentance.
وسبحانك اللهم وبحمدك أشهد أن لا إله إلا أنت أستغفرك وأتوب إليك
