Chapter on Rulings on Forgetfulness (Sahw) in Prayer and What Requires Repeating of Prayer

فَأَمَّا مَا رَوَاهُ أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى عَنِ اَلْبَرْقِيِّ عَنْ سَعْدِ بْنِ سَعْدٍ اَلْأَشْعَرِيِّ قَالَ قَالَ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: «فِي سَجْدَتَيِ اَلسَّهْوِ إِذَا نَقَصْتَ قَبْلَ اَلتَّسْلِيمِ وَ إِذَا زِدْتَ فَبَعْدَهُ»
As for what was narrated by Ahmad bin Muhammad bin ‘Isa, from al-Barqi, from Sa‘d bin Sa‘d al-Ash‘ari, who said: (Imam) Al-Ridha عليه السلام, peace be upon him, said: "In the two prostrations of forgetfulness (‘sajdatay al-sahw’), if there was a deficiency (in the prayer), then they are before the ‘taslim’; and if there was an addition, then they are after it."
