عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَرْكَعُ رَكْعَتَيْنِ بَعْدَ الْوِتْرِ وَهُوَ جَالِسٌ
It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him and his family) used to perform two rak‘ahs sitting after the Witr prayer.
