Musannaf Ibn Abi Shayba 3:4674

Hushaym narrated to us, from Yahya ibn Sa'id, who said: Muhammad ibn Yahya ibn Habban narrated to us, saying: The Prophet (may Allah bless him and grant him peace) remained for forty mornings performing Qunut in the morning prayer after the bowing (ruku'). He used to say in his Qunut: "O Allah, save al-Walid ibn al-Walid, 'Ayyash ibn Abi Rabi'ah, al-'As ibn Hisham, and the oppressed among the believers in Makkah, who cannot devise a plan nor find a way."
