"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
