Musnad Abu Ya'la al-Mawsili 164:9

Abu Bakr ibn Abi Shaybah narrated to us, Sharik narrated to us, from Abu Ishaq, from Burayd ibn Abi Maryam, from Abu al-Hawra’, from al-Hasan ibn Ali, who said: My grandfather, the Messenger of Allah (may Allah bless him and grant him peace), taught me words to say in the Qunut of the Witr: "O Allah, grant me wellness among those to whom You have granted wellness, and take charge of me among those whom You have taken charge of, and guide me among those whom You have guided, and protect me from the evil of what You have decreed. For indeed, You decree and none can decree against You, and indeed, he whom You befriend is not humiliated. Exalted are You, Blessed and Exalted."
