Calling out Three Takbeers in the Janaazah salaah

Q: Janaa'iz-42: Will the Janaazah salaah be valid if the Imaam made Salaam after calling out only three Takbeers? Will it need to be repeated?

Answer: The Jan aazahsalaah in the stated case is invalid and will have to be repeated. If a person mistakenly made Salaam after three Takbeers and then realised the error, the salaah will be valid if immediately makes the fourth Salaam. This is on condition that between the Salaam and the fourth Takbeer he does not do anything that nullifies salaah such as talking or turning away from the Qibla. There is no necessity for Sajdah Sahw in the Janaazah salaah.
