Mukhtasar Bukhari (Abridged) 2073 — What to recite before sleeping

It is narrated from Sayyiduna Hudhaifah bin Yaman (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings of Allah be upon him) would go to his bed, he would recite this supplication: "(O Allah! In Your name I die and I live.)" And when he would wake up, he would recite this supplication: "All praise is for Allah who gave us life after causing us to die (i.e., sleep), and to Him is the return (after rising from the graves)."
