It was narrated from Ubayy bin Ka’b that:
The Messenger of Allah (ﷺ) used to pray witr with three rak’ahs.
In the first he would recite: “Glorify the Name of Your Lord, the Most High”
in the second: “Say: O you disbelievers!“, and
in the third: “Say: He is Allah, (the) One“.
And he would say the Qunut before bowing,
and when he finished he would say: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy) three times, elongating the words the last time.

” Ibn Shihab informed me, saying: ‘Ata bin Yazid narrated to me from Abu Ayyub: That
the Prophet (ﷺ) said: ‘Witr is a duty, and
1. whoever wants to pray witr with seven (rak’ahs), let him do so;
2. whoever wants to pray witr with five, let him do so,
3. whoever wants to pray witr with three, let him do so; and
4. whoever wants to pray witr with one, let him do so.'”

was narrated that Abu Al-Jawza said:
“Al-Hasan said: “The Messenger of Allah (ﷺ) taught me some words to say in witr in Qunut:
Allahumma ihdini fiman hadayta wa ‘afini fiman afayta wa tawallani fiman tawallayta wa barik li fima a’tayta, wa qini sharra ma qadayta, fa innaka taqdi wa la yuqda ‘alayk, wa innahu la yadhilluman walayta, tabarakta Rabbana wa at’alayt (O Allah, guide me among those whom You have guided, pardon me among those You have pardoned, turn to me in friendship among those on whom You have turned in friendship, and bless me in what You have bestowed, and save me from the evil of what You have decreed. For verily You decree and none can influence You; and he is not humiliated whom You have befriended. Blessed are You, O Lord, and Exalted.)'”
