If the iqamah is called while I am praying a voluntary prayer, how do I break it off: do I say the taslim, or do I leave without saying it?

Question:
Honorable Shaykh, may Allah grant you success, he says: When the iqamah is called, there is no prayer except the obligatory one. You mentioned, may Allah preserve you, that one breaks off the prayer. He asks: How is it broken off? Is it by saying the taslim?

Answer:
It is all the same; he breaks it off with the taslim or without the taslim. The important thing is that he breaks it off. Yes.
