Two prostrations of inadvertence

1. Omission or Addition: If a worshipper inadvertently omits a compulsory action (farz) or adds a non-obligatory action (nafl), the prostrations serve to rectify this lapse. For instance, forgetting a rak’ah (unit of prayer) would necessitate these corrections.

2. Doubt in Prayer: When one experiences uncertainty regarding the number of rak’ahs performed, whether it be a lapse in memory or fading concentration, engaging in Sajdat Sahw reinstates the integrity of the prayer.

3. Errors in Recitation: Mishaps in the recitation of verses during prayer, such as a mispronunciation of Surah or failure to recite a designated portion correctly, may also invoke the need for these prostrations. This serves as a reminder of the importance of clarity and reverence in worship.
