Musannaf Ibn Abi Shayba 33:1177

Jarir narrated to us, from Muhammad ibn Suqah, from Ibrahim, who said: If a man says when he enters the morning, "I seek refuge in the All-Hearing, the All-Knowing, from the accursed Satan," ten times, he is granted protection from Satan until he enters the evening. And if he says it when he enters the evening, he is granted protection from Satan until he enters the morning.
