Machine translationRead the Arabic original
Question:
The questioner says: An imam forgot an obligatory element of the prayer, and before the closing salam he remembered it, but he intentionally left out the prostration for forgetfulness, knowing the ruling. What is the ruling on his action? He says that anything other than the pillars does not invalidate the prayer.
Answer:
If he intentionally leaves out an obligatory element, his prayer is not invalidated. If he intentionally leaves out the sitting between the first tashahhud, or intentionally leaves out the sitting for the first tashahhud, his prayer is invalidated, even though the first tashahhud is obligatory. However, if he forgets it, he makes it up with the two prostrations for forgetfulness. Yes.
