Musnad Ahmad 339:0

Narrated to us by Yazid, who said: Narrated to us by Muhammad ibn Ishaq, from Yazid ibn Abi Habib, from Marthad ibn Abdullah al-Yazani, from Abu Abd al-Rahman al-Juhani, that al-Walid ibn al-Walid came to the Messenger of Allah (ﷺ) and said: "O Messenger of Allah, I suffer from loneliness." The Messenger of Allah (ﷺ) said to him: "When you go to your bed, say: 'I seek refuge in the perfect words of Allah from His anger, the evil of His servants, the incitements of the devils, and that they should attend me.'" He said: "So he said it, and it departed from him."
