The ruling on a person obligated to pray leading a voluntary prayer

The questioner : If the imam says it is obligatory except for a voluntary prayer, here it is not valid, because it is not permissible for the one obligated to pray to perform a voluntary prayer, may Allah grant you success?

The Shaykh : That he prays, that the one obligated to pray follows the imam according to a school of jurisprudence.

The questioner : Yes, and there is no condition in this, is this correct?

The Shaykh : No, based on the school of jurisprudence, but according to the second opinion, there is no harm.

The questioner : Meaning, it is predominant. Now, I say for a second reason that even the imam misses the congregation,

The Shaykh : Yes, perhaps. In this case, perhaps we say he may be excused. He may be excused, otherwise yes, if we attribute it to this, we say it is not permissible absolutely.

The questioner : Meaning, the ruling is that there is nothing except for what.

The Shaykh : If this is the cause, then if it is permissible for him to turn it into a voluntary prayer, it depends on the difference in intention between the imam and the one following him.
