Musnad Ahmad 1718

It was narrated from Abul-Hawra" that al-Hasan bin "Ali said: The Messenger of Allah (ﷺ) taught me some words to say in Qunootal-Witr "O Allah, guide me along with those whom You have guided, pardon me along with those whom You have pardoned, protect me along with those whom You protect, and bless for me that which You have bestowed. Protect me from the evil You have decreed, for verily, You decree and none can decree over You. For surety, he whom You protect is never abased. O our Lord, Blessed and Exalted are You.”
