If the ma'mum (one praying behind the imam) lags behind the imam due to an excuse, what is the ruling on his prayer?

The questioner : All right, lagging behind. Here you are. Lagging behind. If he lags behind the imam until the imam finishes the pillar, and the ma'mum gets out of the imam's pillar before the prayer is complete? Yes.

The Shaykh : There is no distinction before that.

The questioner : He was acting.

The Shaykh : If he was ignorant or forgetful.

The questioner : If he was ignorant or forgetful.

The Shaykh : Yes.

The questioner : There are two cases: either the imam finishes the pillar before the ma'mum starts it, or the imam lags behind the ma'mum with a clear delay.

The Shaykh : It has several scenarios. First, if the imam finishes all the pillars and returns to the same pillar where the ma'mum was, it counts as a combined rak'ah for him, meaning he catches up with his imam. If he lagged behind his imam due to an excuse, he catches up with him, right? Provided the imam has not reached his position. If the imam reaches his position, the second rak'ah for the imam becomes the first for him. Is that clear or not? All right, have we finished with this or not?
