Answered by Sidi Moustafa Elqabbany
My question is relating to joining the prayer in the 4th raka’ of a congregational prayer. How does one get up and pray the missed portion? I guess I’m asking whether the 4th raka counts as the 1st raka’ or the 4th raka’?
If you catch ruku’ with the imam, that is your first rak’ah and his fourth. If you join the prayer after he has begun to rise from ruku’, you’ve missed the rak’ah and your first rak’ah will be the next one you pray.
The above is true regardless of whether one joins the prayer at its start or end.
Allah the Exalted knows best.
