[Machine] The Prophet ﷺ used to pray two rak'ahs after Witr while sitting, and in them he would recite (the surah) 'When the earth is shaken' and (the surah) 'Say: O disbelievers'.
أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي رَكْعَتَيْنِ بَعْدَ الْوِتْرِ وَهُوَ جَالِسٌ يَقْرَأُ فِيهِمَا إِذَا زُلْزِلَتْ وَقُلْ يَا أَيُّهَا الْكَافِرُونَ
