إِذَا قُمْتَ فِي الرَّكْعَتَيْنِ مِنَ الظُّهْرِ أَوْ غَيْرِهِمَا وَ لَمْ تَتَشَهَّدْ فِيهِمَا فَذَكَرْتَ ذَلِكَ فِي الرَّكْعَةِ الثَّالِثَةِ قَبْلَ أَنْ تَرْكَعَ فَاجْلِسْ فَتَشَهَّدْ وَ قُمْ فَأَتِمَّ صَلَاتَكَ فَإِنْ أَنْتَ لَمْ تَذْكُرْ حَتَّى تَرْكَعَ فَامْضِ فِي صَلَاتِكَ حَتَّى تَفْرُغَ فَإِذَا فَرَغْتَ فَاسْجُدْ سَجْدَتَيِ السَّهْوِ بَعْدَ التَّسْلِيمِ قَبْلَ أَنْ تَتَكَلَّمَ.
“Abu ‘Abd Allah (a.s.) has stated this Hadith. He (the Imam) has said, ‘You may stand up in the two Rak‘at of al-Dhuhr or others without saying Tashahhud (testimonies of belief) and remember it in the third Rak‘at before Ruku‘ (bowing down on one’s knees), you must sit down, then say Tashahhud (testimonies of belief),
