[Machine] The Prophet ﷺ used to pray in the month of Ramadan, outside of congregational prayers, with twenty units (rak'ahs) and would pray the odd (witr) prayer separately. Abu Shu'aybatah Ibrahim ibn Uthman al-Abssi al-Kufi performed this prayer alone, and he was weak.
كَانَ النَّبِيُّ ﷺ يُصَلِّي فِي شَهْرِ رَمَضَانَ فِي غَيْرِ جَمَاعَةٍ بِعِشْرِينَ رَكْعَةٍ وَالْوِتْرِ تَفَرَّدَ بِهِ أَبُو شَيْبَةَ إِبْرَاهِيمُ بْنُ عُثْمَانَ الْعَبْسِيُّ الْكُوفِيُّ وَهُوَ ضَعِيفٌ
