Mukhtasar Bukhari (Abridged) 2074 — Sleeping on the right side

Narrated from Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings of Allah be upon him) would go to bed to sleep, he would lie on his right side and recite this supplication: “O Allah, I have submitted my soul to You, I have turned my face fully towards You, I have entrusted all my affairs to You, my reliance is upon You, I desire only Your grace and mercy, and there is no refuge or escape from Your punishment except with You. I believe in Your Book which You have revealed and in Your Prophet (peace and blessings of Allah be upon him) whom You have sent.”
