The ruling on one who joins the imam in the third rak'ah and completes the prayer with them
Machine translationRead the Arabic original
The questioner : May Allah bless you. We say that he builds upon the prayer of the first day, meaning he prays a new prayer.
The Shaykh : No, he builds upon the first prayer. If he missed any part of it, he makes it up. The people who have completed their prayer sit down. For example, if the imam joins them while they are in the third rak'ah, he prays with them the remainder, then he stands up while they sit waiting for his taslim.
The questioner : Where is the building here? So where is the building here? I mean, how did he build upon it when he started his prayer a little late?
The Shaykh : By "building," I mean that he did not say the takbir of ihram and did not restart. Did he restart the congregation?
The questioner : But when is the prayer of the house?
The Shaykh : He is ill and starts, but as for the praying people, they remain as they are. Yes.
