Chapter on the Detailed Explanation of Prayer, Including the Obligatory and Recommended, and What is Permissible and Not Permissible.
اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ اِبْنِ مُسْكَانَ عَنْ أَبِي بَصِيرٍ قَالَ: سَأَلْتُهُ عَمَّنْ نَسِيَ أَنْ يَسْجُدَ سَجْدَةً وَاحِدَةً فَذَكَرَهَا وَ هُوَ قَائِمٌ قَالَ« يَسْجُدُهَا إِذَا ذَكَرَهَا مَا لَمْ يَرْكَعْ فَإِنْ كَانَ قَدْ رَكَعَ فَلْيَمْضِ عَلَى صَلاَتِهِ وَ إِذَا اِنْصَرَفَ قَضَاهَا وَ لَيْسَ عَلَيْهِ سَهْوٌ»
Al-Husayn ibn Sa’id from Muhammad ibn Sinan from Ibn Muskan from Abu Basir, who said:
I asked Him عليه السلام about someone who forgets to perform one prostration and remembers it while standing. Imam عليه السلام said: "Let him perform the prostration when he remembers it, as long as he has not yet bowed. But if he has already bowed, then let him continue with his prayer, and when he finishes, he should make it up, and there is no prostration of forgetfulness (sajdat al-sahw) upon him."
