Mukhtasar Bukhari (Abridged) 2076 — Book of Supplications

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When any of you comes to his bed to sleep, he should dust it off, for he does not know what may have entered it after he left. Then he should recite this supplication: 'My Lord! In Your blessed name I lay my side on the bed, and in Your blessed name I will lift it (in the future). If You withhold my soul in this state (if I die), then have mercy on it, and if You release it, then protect it (from sins) as You protect Your righteous servants.'"
