[Machine] The Messenger of Allah ﷺ said, "When one of you prays, he does not know whether he has prayed three or four (rak'ahs). So let him perform one extra rak'ah, perfecting its prostration and bowing, and then make two prostrations."  

قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا صَلَّى أَحَدُكُمْ فَلَا يَدْرِي كَمْ صَلَّى ثَلَاثًا أَمْ أَرْبَعًا فَلْيَرْكَعْ رَكْعَةً يُحْسِنُ سُجُودَهَا وَرُكُوعَهَا ثُمَّ يَسْجُدُ سَجْدَتَيْنِ»  

[Machine] The translation of the given text in English is: "The Messenger of Allah, peace be upon him, said: 'When one of you prays and doesn't know how much he has prayed, whether it is three or four (raka'at), let him perform one additional raka'ah, perfecting its bowing and prostration, and then make two prostrations.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِذَا صَلَّى أَحَدُكُمْ فَلَا يَدْرِي كَمْ صَلَّى ثَلَاثًا أَوْ أَرْبَعًا فَلْيَرْكَعْ رَكْعَةً يُحْسِنُ رُكُوعَهَا وَسُجُودَهَا وَيَسْجُدُ سَجْدَتَيْنِ»  

[Machine] The Messenger of Allah ﷺ said, "When one of you prays, he does not know whether he has prayed three or four rak'ahs, so let him prostrate a rak'ah, performing its bowing and prostration well, and then let him perform two prostrations. Its narrators are trustworthy, and Malik ibn Anas has confirmed it in Al-Muwatta."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ فَلَا يَدْرِي كَمْ صَلَّى ثَلَاثًا أَمْ أَرْبَعًا فَلْيَرْكَعْ رَكْعَةً يُحْسِنُ رُكُوعَهَا وَسُجُودَهَا ثُمَّ يَسْجُدُ سَجْدَتَيْنِ رُوَاتُهُ ثِقَاتٌ وَقَدْ وَقَفَهُ مَالِكُ بْنُ أَنَسٍ فِي الْمُوَطَّأِ
