The ruling on one who forgets a pillar in the prayer
Machine translationRead the Arabic original
Question:
What about the one who forgot a pillar in four rak'ahs and then remembered? Does he pray the prayer, or does he perform a complete rak'ah after the prayer?
Answer:
If one forgets a pillar in a rak'ah of the prayer and does not remember it until after he has prayed, he stands up and performs a complete rak'ah and prostrates for forgetfulness. As for if he remembers that he left out a pillar while he is still in the prayer, the rak'ah in which he left it out is replaced by the one that follows it; he repeats the rak'ah in which he left it out, and the one that follows it takes its place. He completes his prayer in this manner and prostrates for forgetfulness.
