´It was narrated that Abu Salamah said:` “Aishah narrated to me that the Messenger of Allah (ﷺ) prayed Witr with one Rak’ah, then he prayed two Rak’ah in which he recited while sitting, then when he wanted to bow, he stood up and bowed.”

Benefit:
It is permissible to perform two rak‘ahs after the witr prayer, which may be offered either sitting or standing. However, without a valid excuse, performing prayer while sitting yields only half the reward. (: Sahih al-Bukhari, Kitab al-Taqsir, Chapter: The Prayer of One Who Sits, Hadith: 1115)
