Musannaf Ibn Abi Shayba 21:627

Sharik narrated to us, from Abu Ishaq, from Abu Ubaydah, that Ali used to say when he saw the crescent moon: "O Allah, grant us its beginning [O Allah, I ask You for the opening of this month and its good], its victory, its blessing, and its light. And we seek refuge in You from its evil and the evil of what follows it."
