Al-Hasan ibn 'Ali said: The Messenger of Allah, peace and blessings be upon him, taught me words to say in the Witr prayer — Ibn Jawwas said: in the qunut of the Witr —: "O Allah, guide me among those whom You have guided, and grant me well-being among those whom You have granted well-being, and take charge of me among those whom You have taken charge of, and bless for me what You have given, and protect me from the evil of what You have decreed. Indeed, You decree and nothing is decreed against You. Indeed, he whom You support is not humiliated. Blessed are You, our Lord, and exalted are You."(1)

1426 — 'Abdullah ibn Muhammad al-Nufayli narrated to us, Zuhayr narrated to us, Abu Ishaq narrated to us, with his chain of transmission and its meaning, and he said at its end: He said: This is what he says in the Witr in the qunut, and he did not mention: "I say them in the Witr."

Abu al-Hawra': Rabi'ah ibn Shayban(2).

--------------------------------------------
(1) Its chain of transmission is sound. Abu al-Ahwas: he is Sallam ibn Sulaym, and Abu Ishaq: he is 'Amr ibn 'Abdullah al-Sabi'i, and Abu al-Hawra': he is Rabi'ah ibn Shayban al-Sa'di.
It was also recorded by al-Tirmidhi (468), and al-Nasa'i in "al-Kubra" (1446) via the route of Qutaybah ibn Sa'id, with this chain of transmission, and al-Tirmidhi said: This is a good hadith that we only know from this route, from the hadith of Abu al-Hawra' al-Sa'di. Al-Nawawi declared it sound in "al-Khulasah" (1499).
It was also recorded by Ibn Majah (1178) via the route of Sharik, from Abu Ishaq, with it. And he said: I say them in the qunut of the Witr.
It was also recorded by al-Nasa'i (1447) via the route of Ibn Wahb, from Yahya ibn 'Abdullah ibn Salim, from Musa ibn 'Uqbah, from 'Abdullah ibn 'Ali, from al-Hasan, with it. This is a strong chain of transmission, and al-Hakim declared it sound, 3/172.
It is in "Musnad Ahmad" (1718), and "Sahih Ibn Hibban" (945).
See what follows it.

(2) Its chain of transmission is sound. Zuhayr: he is Ibn Mu'awiyah al-Ju'fi.
It was also recorded by Ibn al-Jarud (273), al-Bazzar (1337), al-Tabarani in "al-Kabir" (2704), and al-Bayhaqi 2/498 via multiple routes from Zuhayr ibn Mu'awiyah, with this chain of transmission.
