Chapter on Rulings on Forgetfulness (Sahw) in Prayer and What Requires Repeating of Prayer
اَلْحَسَنُ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ قَالَ:« إِذَا سَهَا اَلرَّجُلُ فِي اَلرَّكْعَتَيْنِ اَلْأَوَّلَتَيْنِ مِنَ اَلظُّهْرِ وَاَلْعَصْرِ وَلَمْ يَدْرِ وَاحِدَةً صَلَّى أَمْ ثِنْتَيْنِ فَعَلَيْهِ أَنْ يُعِيدَ اَلصَّلاَةَ»
Al-Hasan, from Zur‘ah, from Sama‘ah, who said:
Imam عليه السلام said: "If a man is forgetful in the first two rak‘ahs of the Dhuhr and ‘Asr prayers and does not know whether he prayed one or two, then it is obligatory upon him to repeat the prayer."
