Leaving a pillar of the prayer and then remembering it
Machine translationRead the Arabic original
Question:
Or, O Abu al-Shaykh, a person prayed the four-rak'ah prayer, then left out the sitting between the two tashahhuds. That is, he stood up for the second rak'ah, then was reminded, so he went back to the second tashahhud without sitting and without saying the words of the standing. What is required of you now? Because he was ignorant of the ruling.
Answer:
If one leaves out a pillar of the prayer, and he remembers it while the time is still close to the prayer, he performs a rak'ah and prostrates for it. If the time has passed and the interval has become long, he repeats the entire prayer.
