A man entered the Mosque while the Prophet ﷺ was delivering the Khutba. The Prophet ﷺ said to him, "Have you prayed?" The man replied in the negative. The Prophet ﷺ said, "Pray two rakʿat."  

دَخَلَ رَجُلٌ يَوْمَ الْجُمُعَةِ وَالنَّبِيُّ ﷺ يَخْطُبُ فَقَالَ: «أَصَلَّيْتَ؟» قَالَ: لاَ۔ قَالَ: «فَصَلِّ رَكْعَتَيْنِ۔»
