Q: A person I know came with me to the Friday prayers. He is not very knowledgeable in Fiqh like myself and we are both non-Aalims. I got out and my companion went to park, but time was running short already, so I managed to find a space, but wasn’t sure whether my companion got there on-time. Anyway, I prayed and finished the namaaz. When I got towards the back row I noticed my companion, he pulled me to the side and he was concerned if his prayer was valid, he explained to me the following situation: He came and the Jamaat rose for the 2nd rak’ah, he joined them in the 2nd rak’ah. So when they went into Tashahhud and my companion got up before the Imaam made tasleem, either out of forgetfulness or ignorance, and he quickly managed to finish his final rak’ah and apparently still managed to say the tasleem with the Imaam. He didn’t do two prostrations of forgetfulness either. If he neglected to say the Tashahhud out of ignorance as well, would that affect the verdict? What is the verdict anyway?
A: If he read the tashahhud, the salaah will be valid but doing so is makrooh-e-tahreemi. Otherwise the salaah will not be valid and it will have to be repeated.
And Allah Ta’ala (الله تعالى) knows best.
