[Machine] The Messenger of Allah ﷺ said, "If one of you prays and does not know how many units of prayer they have performed, they should perform two prostrations. If the Satan approaches them and says, 'You have made a mistake,' they should say, 'I have not, except for what I detected in my nose or heard in my ear.'"
قَالَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ فَلَمْ يَدْرِ كَمْ صَلَّى فَلْيَسْجُدْ سَجْدَتَيْنِ فَإِنْ أَتَاهُ الشَّيْطَانُ فَقَالَ إِنَّكَ قَدْ أَحْدَثْتَ فَلْيَقُلْ كَذَبْتَ إِلَّا مَا وَجَدَ رِيحًا بِأَنْفِهِ أَوْ صَوْتًا بِأُذُنِهِ
