Joining the Salaah while the Imaam is coming up from ruku
Q: I joined the Asr salaah when the Imam was coming up from ruku in the second rakaat. While he was coming up from ruku I joined the Salaah and went into ruku by accident. At the end of the salaah, I stood up and completed two rakaats and made sajda-e-sahw. Is the Salaah valid?
