Question:
And if two people ask the imam and do not know, and after the taslim a little while has passed, I wrote to the imam, but there is a triangle that completes the prayer, so they said he completes his prayer without knowing the imam’s secret. Does he complete his prayer alone? Or is it obligatory for him to return to every part of the imam?
Answer:
He has the choice: if he wishes, he completes his prayer alone, because he has separated from the imam; and if he wishes, he joins the imam and completes it with him.
