Chapter on the Detailed Explanation of Prayer, Including the Obligatory and Recommended, and What is Permissible and Not Permissible.
وَعَنْهُ عَنِ اَلْقَاسِمِ بْنِ مُحَمَّدٍ عَنِ اَلْحُسَيْنِ [اَ لْ حُ سَ يْ نِ خ ل] بْنِ أَبِي اَلْعَلاَءِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلرَّجُلِ يُصَلِّي رَكْعَتَيِ اَلْمَكْتُوبَةِ فَلاَ يَجْلِسُ حَتَّى يَرْكَعَ فِي اَلثَّالِثَةِ قَالَ« يُتِمُّ صَلاَتَهُ وَ يَسْجُدُ سَجْدَتَيِ اَلسَّهْوِ وَ هُوَ جَالِسٌ قَبْلَ أَنْ يَتَكَلَّمَ»
And from him, from al-Qasim ibn Muhammad, from al-Husayn ibn Abi al-‘Ala’, from Abu Abdillah عليه السلام, peace be upon him, who said:
I asked Him عليه السلام about a man who performs the two rak‘ahs of the obligatory prayer but does not sit until he bows in the third (rak‘ah). Imam عليه السلام said: "He should complete his prayer and perform the two prostrations of forgetfulness (sajdatay al-sahw) while he is seated, before he speaks."
