The ruling on one who stands for the third rak'ah without the first tashahhud
Machine translationRead the Arabic original
Question:
He says: If the imam does not sit for the first tashahhud in a four-rak'ah prayer, and then stands for the third rak'ah and straightens up, what is the ruling, and what is obligatory for him?
Answer:
He continues standing and completes the prayer, then he performs the prostration for forgetfulness before the taslim. He performs two prostrations for forgetfulness, as the Prophet (peace and blessings be upon him) did when this happened to him: he stood up from the two rak'ahs without performing the tashahhud, then he performed the prostration for forgetfulness before he said the taslim. Yes.
