What is the ruling on the prayer of one who said the taslim in the final tashahhud before the imam?

The permissibility of leading congregational prayers in homes is derived from authentic hadiths, including what Muslim narrated from Anas regarding the Prophet's prayer in their home, and what Jabir and Ibn Mas'ud (may Allah be pleased with them both) did. The hadith (definition), "A man should not lead prayer in another's house, nor in his domain," means that the owner of the house has a greater right to lead the prayer.
