[Machine] Teach me, O Messenger of Allah, what to say in my Witr prayer when I raise my head and only Sujood remains (to be performed). O Allah, guide me among those whom You have guided, make me well among those whom You have made well, take care of me among those whom You have taken care of, bless me in what You have given me, and protect me from the evil that You have decreed. Indeed, You decree and none can decree upon You. No one who You have befriended will be humiliated, and no one who You have opposed will be honored. Blessed are You, our Lord, and Exalted are You. This wording is specific to Abu Bakr ibn Shaybah al-Hazami, and it has been narrated in the Qunut of the Fajr prayer after the Ruku'. It is what is recommended to rely upon, and the Qunut of Witr prayer is based on it by analogy.
عَلِّمْنِي رَسُولُ اللهِ ﷺ فِي وِتْرِي إِذَا رَفَعْتُ رَأْسِي وَلَمْ يَبْقَ إِلَّا السُّجُودُ اللهُمَّ اهْدِنِي فِيمَنْ هَدَيْتَ وَعَافِنِي فِيمَنْ عَافَيْتَ وَتَوَلَّنِي فِيمَنْ تَوَلَّيْتَ وَبَارِكْ لِي فِيمَا أَعْطَيْتَ وَقِنِي شَرَّ مَا قَضَيْتَ إِنَّكَ تَقْضِي وَلَا يُقْضَى عَلَيْكَ إِنَّهُ لَا يَذِلُّ مَنْ وَالَيْتَ وَلَا يَعِزُّ مَنْ عَادَيْتَ تَبَارَكْتَ رَبَّنَا وَتَعَالَيْتَ تَفَرَّدَ بِهَذَا اللَّفْظِ أَبُو بَكْرِ بْنُ شَيْبَةَ الْحِزَامِيُّ وَقَدْ رُوِّينَا فِي قُنُوتِ صَلَاةِ الصُّبْحِ بَعْدَ الرُّكُوعِ مَا يُوجِبُ الِاعْتِمَادَ عَلَيْهِ وَقُنُوتُ الْوِتْرِ قِيَاسٌ عَلَيْهِ
