The ruling on one who leaves a pillar in the third rak'ah and begins the fourth

The questioner:
Honorable Shaykh, may Allah grant you success, if I left a pillar in the third rak'ah and started the fourth, are the first two rak'ahs invalidated?

The Shaykh:
No, the third rak'ah is severed, the third rak'ah is severed, and you make the fourth the third,

The questioner:
The Shaykh's misfortune.

The Shaykh:
The rak'ah in which he left it is invalidated, and the one following it takes its place. This is the general rule: the first rak'ah, and in the second, and in the third, and in the fourth,
