Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ حَدَّثَنَا الدَّسْتُوَائِيُّ حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ حَدَّثَنَا عِيَاضٌ قَالَ قُلْتُ لِأَبِي سَعِيدٍ الْخُدْرِيِّ أَحَدُنَا يُصَلِّي فَلَا يَدْرِي كَمْ صَلَّى فَقَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا صَلَّى أَحَدُكُمْ فَلَمْ يَدْرِ كَمْ صَلَّى فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ وَإِذَا جَاءَ أَحَدَكُمْ الشَّيْطَانُ فَقَالَ إِنَّكَ قَدْ أَحْدَثْتَ فَلْيَقُلْ كَذَبْتَ إِلَّا مَا وَجَدَ رِيحَهُ بِأَنْفِهِ أَوْ سَمِعَ صَوْتَهُ بِأُذُنِهِ.
English Translation
Isma'il told us, al-Dastawa'i told us, Yahya ibn Abi Kathir told me, Iyad told us, who said: I said to Abu Sa'id al-Khudri: "One of us prays but does not know how many rak'ahs he has prayed." He said: The Messenger of Allah, peace and blessings be upon him, said: "If one of you prays and does not know how many rak'ahs he has prayed, let him prostrate twice while seated. And if Satan comes to one of you and says: 'You have broken your ablution,' let him say: 'You have lied' — unless he found its smell with his nose or heard its sound with his ear."
