• The Imam's mistake: If the Imam makes a forgetful error that requires Sujud al-Sahw, the follower performs Sujud al-Sahw with the Imam.
• The follower's own mistake: If the follower makes an individual forgetful error while following the Imam, the follower does not perform a separate Sujud al-Sahw for that error.
• Rule: The follower is bound to the Imam in congregational prayer: the follower follows the Imam in the Imam's Sujud al-Sahw, but does not prostrate independently for the follower's own mistake.

Lesson

1. Sujud al-Sahw in Congregation

وَيَلْزَمُ الْمَأْمُومَ بِسَهْوِ إِمَامِهِ لَا بِسَهْوِ نَفْسِهِ
• The Imam's mistake: If the Imam makes a forgetful error that requires Sujud al-Sahw, the follower performs Sujud al-Sahw with the Imam.
• The follower's own mistake: If the follower makes an individual forgetful error while following the Imam, the follower does not perform a separate Sujud al-Sahw for that error.
• Rule: The follower is bound to the Imam in congregational prayer: the follower follows the Imam in the Imam's Sujud al-Sahw, but does not prostrate independently for the follower's own mistake.

2. Latecomers and Sujud al-Sahw Rules

وَيَسْجُدُ الْمَسْبُوقُ مَعَهُ فِيمَا يَقْضِيهِ أَيْضًا لَا اللَّاحِقُ
• Masbuq (latecomer): A latecomer follows the Imam in the Imam's Sujud al-Sahw, even if the Imam's mistake occurred before the latecomer joined.
• If the Masbuq makes a mistake requiring Sujud al-Sahw while completing missed units after the Imam's salam, the Masbuq performs Sujud al-Sahw at the end.
• Lahiq: A follower who began with the Imam but missed part of the prayer because of an excuse remains legally attached to the Imam while making up that missed portion and does not perform a separate Sujud al-Sahw for an individual mistake there.

3. Stand-up Errors from the First Sitting

وَمَنْ سَهَا عَنِ الْقُعُودِ الأَوَّلِ مِنَ الْفَرْضِ عَادَ إِلَيْهِ مَا لَمْ يَسْتَوِ قَائِمًا
• The First Sitting (al-Qa'dah al-Ula): If a worshipper forgetfully begins to stand up for the third unit of a Fard prayer, omitting the necessary first sitting:
◦ Closer to Sitting (Aqrabu ila al-Qu'ud): If they are still closer to the sitting posture, they must immediately return to the sitting. No Sujud al-Sahw is required of them.
◦ Closer to Standing or Standing Fully (Istawa Qa'iman): If they have stood up straight, or are closer to the standing posture, they must not return to the sitting position.
• Rectification: They must complete their prayer normally and are legally required to perform Sujud al-Sahw at the end.

4. Errors in the Final Sitting

وَإِنْ سَهَا عَنِ الْقُعُودِ الأَخِيرِ عَادَ مَا لَمْ يَسْجُدْ لِلْخَامِسَةِ
• The Final Sitting (al-Qa'dah al-Akhirah): If a worshipper forgetfully stands up for an extra unit (e.g., a fifth unit in a four-unit Fard prayer) without performing the final sitting:
◦ Before Prostrating for the Extra Unit: If they remember before performing the prostration (Sujud) of the fifth unit, they must return to the sitting posture, recite the Tashahhud, and perform Sujud al-Sahw at the end.
◦ After Prostrating for the Extra Unit: If they have already performed the prostration of the fifth unit, their Fard prayer is invalidated (Batalat) and converted entirely into a voluntary (Nafal) prayer.
• Nafal Completion: It is recommended to add a sixth unit so that the voluntary units become an even-numbered set.

5. Doubt About the Number of Rak'ahs

بُطْلَتِ الصَّلَاةُ بِالشَّكِّ فِي عَدَدِ رَكَعَاتِهَا إِذَا كَانَ قَبْلَ إِكْمَالِهَا... وَإِنْ كَثُرَ الشَّكُّ عَمِلَ بِغَالِبِ ظَنِّهِ
