Hadith 1240
أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ ، قَالَ : حَدَّثَنَا حُجَيْنُ بْنُ الْمُثَنَّى ، قَالَ : حَدَّثَنَا عَبْدُ الْعَزِيزِ وَهُوَ ابْنُ أَبِي سَلَمَةَ ، عَنْ زَيْدِ بْنِ أَسْلَمَ ، عَنْ عَطَاءِ بْنِ يَسَارٍ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ : " إِذَا لَمْ يَدْرِ أَحَدُكُمْ صَلَّى ثَلَاثًا أَمْ أَرْبَعًا فَلْيُصَلِّ رَكْعَةً ، ثُمَّ يَسْجُدْ بَعْدَ ذَلِكَ سَجْدَتَيْنِ وَهُوَ جَالِسٌ , فَإِنْ كَانَ صَلَّى خَمْسًا شَفَعَتَا لَهُ صَلَاتَهُ , وَإِنْ صَلَّى أَرْبَعًا كَانَتَا تَرْغِيمًا لِلشَّيْطَانِ " .
´It was narrated from Abu Sa'eed Al-Khudri that:` The Prophet (ﷺ) said: "If one of you does not know whether he prayed three or four (rak'ahs), let him pray a rak'ah then prostrate twice after that when he is sitting. Then if he 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."
