Two are the prayers which the Messenger of Allah ﷺ always observed in my house-openly or secretly-two rak'ahs before the dawn and two rak'ahs after the 'Asr.
صَلاَتَانِ مَا تَرَكَهُمَا رَسُولُ اللَّهِ ﷺ فِي بَيْتِي قَطُّ سِرًّا وَلاَ عَلاَنِيَةً رَكْعَتَيْنِ قَبْلَ الْفَجْرِ وَرَكْعَتَيْنِ بَعْدَ الْعَصْرِ
Messenger of Allah ﷺ never missed two rakʿat before the Fajr prayer and after the ʿAsr prayer openly and secretly.
رَكْعَتَانِ لَمْ يَكُنْ رَسُولُ اللَّهِ ﷺ يَدَعُهُمَا سِرًّا وَلاَ عَلاَنِيَةً رَكْعَتَانِ قَبْلَ صَلاَةِ الصُّبْحِ وَرَكْعَتَانِ بَعْدَ الْعَصْرِ
"There are two prayers that the Messenger of Allah ﷺ never neglected to pray them in my house secretly nor publicly: Two Rak'ahs before Fajr and two Rak'ahs after 'Asr."
صَلاَتَانِ مَا تَرَكَهُمَا رَسُولُ اللَّهِ ﷺ فِي بَيْتِي سِرًّا وَلاَ عَلاَنِيَةً رَكْعَتَانِ قَبْلَ الْفَجْرِ وَرَكْعَتَانِ بَعْدَ الْعَصْرِ
"There are two prayers that the Messenger of Allah ﷺ never neglected to pray them in my house secretly nor publicly: Two Rak'ahs before Fajr and two Rak'ahs after 'Asr." (Using translation from Nasāʾī 577)
صَلَاتَانِ لَمْ يَتْرُكْهُمَا النَّبِيُّ ﷺ سِرًّا وَلَاعَلَانِيَةً رَكْعَتَيْنِ بَعْدَ الْعَصْرِ وَرَكْعَتَيْنِ قَبْلَ الْفَجْرِ
Two are the prayers which the Messenger of Allah ﷺ always observed in my house-openly or secretly-two rak'ahs before the dawn and two rak'ahs after the 'Asr. (Using translation from Muslim 835c)
«صَلَاتَانِ مَا تَرَكَهُمَا رَسُولُ اللهِ ﷺ فِي بَيْتِي سِرًّا وَلَا عَلَانِيَةً رَكْعَتَانِ قَبْلَ الْفَجْرِ وَرَكْعَتَانِ بَعْدَ الْعَصْرِ»
"عَنْ عَائِشَةَ قَالَتْ: صَلَاتَانِ مَا تَرَكَهُمَا النَّبِيُّ ﷺ فِي بَيْتِي قَطُّ: ركعتين (*) قَبْلَ الفَجْرِ، وَرَكْعَتَيْنِ بَعْدَ العَصْرِ".
