Chapter on Rulings on Forgetfulness (Sahw) in Prayer and What Requires Repeating of Prayer
وَ عَنْهُ عَنِ اَلنَّضْرِ عَنْ مُوسَى بْنِ بَكْرٍ قَالَ: سَأَلَهُ اَلْفُضَيْلُ عَنِ اَلسَّهْوِ فَقَالَ« إِذَا شَكَكْتَ فِي اَلْأُولَيَيْنِ فَأَعِدْ»
And from him, from al-Nadr, from Musa bin Bakr, who said:
Al-Fudayl asked Him عليه السلام about forgetfulness (in prayer). Imam عليه السلام said: "If you are doubtful about first two (rak‘ahs), then repeat (the prayer)."
