أَخْبَرَنَا يَحْيَی بْنُ حَبِيبِ بْنِ عَرَبِيٍّ قَالَ حَدَّثَنَا خَالِدٌ عَنْ ابْنِ عَجْلَانَ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ عَطَائِ بْنِ يَسَارٍ عَنْ أَبِي سَعِيدٍ عَنْ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا شَکَّ أَحَدُکُمْ فِي صَلَاتِهِ فَلْيُلْغِ الشَّکَّ وَلْيَبْنِ عَلَی الْيَقِينِ فَإِذَا اسْتَيْقَنَ بِالتَّمَامِ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ قَاعِدٌ فَإِنْ کَانَ صَلَّی خَمْسًا شَفَعَتَا لَهُ صَلَاتَهُ وَإِنْ صَلَّی أَرْبَعًا کَانَتَا تَرْغِيمًا لِلشَّيْطَانِ
سنن نسائی · Hadith 1243
It was narrated from Abu Saeed that the Prophet صلی اللہ علیہ وآلہ وسلم said: “If one of you is not sure about his prayer, let him forget about what he is unsure of and complete his prayer on the basis of what he is sure of. When he is sure that he has completed it, let him prostrate twice while he is sitting. Then if he has prayed five (Rak’ahs), they (the two prostrations) will make his prayer even-numbered, and if he had prayed four, they will annoy and humiliate the Shaitan.” (Sahih)
