Hadith 174
The Book on Salat (Prayer)
Abdur-Rahman bi Awf narrated that he heard the Prophet (S) saying:
"When one of you becomes forgetful in his Salat so that he does not know if he prayed one or two, then let him consider it one. When he does not know if he prayed three or four, then let him consider it three, and let him perform two prostrations before he says the Taslim."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ خَالِدٍ ابْنُ عَثْمَةَ الْبَصْرِيُّ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ إِسْحَاقَ، عَنْ مَكْحُولٍ، عَنْ كُرَيْبٍ، عَنِ ابْنِ عَبَّاسٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ
إِذَا سَهَا أَحَدُكُمْ فِي صَلاَتِهِ فَلَمْ يَدْرِ وَاحِدَةً صَلَّى أَوْ ثِنْتَيْنِ فَلْيَبْنِ عَلَى وَاحِدَةٍ فَإِنْ لَمْ يَدْرِ ثِنْتَيْنِ صَلَّى أَوْ ثَلاَثًا فَلْيَبْنِ عَلَى ثِنْتَيْنِ فَإِنْ لَمْ يَدْرِ ثَلاَثًا صَلَّى أَوْ أَرْبَعًا فَلْيَبْنِ عَلَى ثَلاَثٍ وَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ
