It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When any one of you wakes up at night and then returns to his bed, he should dust his bed with the edge of his lower garment, for he does not know what may have come onto his bed after him. Then he should say: O Allah, by Your name I have laid my side on the earth, and by Your name I will rise. If You take my soul, then forgive it, and if You send it back, then protect it as You protect Your righteous servants.
