Chapter on Rulings on Forgetfulness (Sahw) in Prayer and What Requires Repeating of Prayer
وَ عَنْهُ عَنْ أَحْمَدَ اَلْقَرَوِيِّ عَنْ أَبَانٍ عَنْ إِسْمَاعِيلَ اَلْجُعْفِيِّ وَ اِبْنِ أَبِي يَعْفُورٍ عَنْ أَبِي جَعْفَرٍ وَ أَبِي عَبْدِ اَللَّهِ عَلَيْهِمَا اَلسَّلاَمُ أَنَّهُمَا قَالاَ:« إِذَا لَمْ تَدْرِ أَ وَاحِدَةً صَلَّيْتَ أَمْ ثِنْتَيْنِ فَاسْتَقْبِلْ»
And from him, from Ahmad al-Qarawi, from Aban, from Isma'il al-Ju'fi and Ibn Abi Ya'fur:
Abu Ja'far عليه السلام and Abu Abdillah عليه السلام, peace be upon them both, they said: "If you do not know whether you prayed one rak‘ah or two, then start over."
