If one leaves out the first tashahhud and adds a ruku', does he prostrate before the taslim?

The questioner : He left out the first tashahhud and added a ruku' in one of the rak'ahs.

The Shaykh : The first is in its place, and the second is after the taslim. So he says: prostrate twice, once before the taslim for leaving out the first tashahhud, and once after it for adding the ruku'. But the madhhab says no, the two prostrations suffice for all of it. But which one takes precedence?

The questioner : Of course. Of course.

The Shaykh : The madhhab holds that what is before the taslim takes precedence because it is more integral to the prayer.
