Musannaf Ibn Abi Shayba 21:71

Yazid ibn Harun narrated to us, Yahya ibn Sa'id informed us, that Muhammad ibn Yahya ibn Habban informed him that his paternal uncle, Abu Sirma, used to narrate that the Messenger of Allah, may Allah bless him and grant him peace, used to say: "O Allah, I ask You for my sufficiency and the sufficiency of my master."
