The ruling on the funeral prayer if the imam forgets the fourth takbir

Question:
Honorable Shaykh, he says: We prayed with an imam over a funeral, but this imam did not perform the fourth takbir; rather, he said the taslim after the third takbir, and he said it on his right side. We did not alert him to it until after the funeral had been lifted. This was a forgetfulness on the part of the imam. The question is: What is the ruling on our prayer? Do we have to repeat the entire prayer, or do we just perform the fourth takbir?

Answer:
If you remember it shortly after the taslim, you perform the fourth takbir and what follows it, and then you say the taslim. However, if you do not remember it until a long time has passed, the prayer over the funeral is repeated from the beginning, because the first prayer was not valid since it was incomplete, so the prayer over it is repeated from the beginning. Yes.
