Hazrat Bara bin Azib narrates that the Noble Prophet (peace and blessings be upon him) said to a man: When you lie down on your bed, say these words: O Allah! I have submitted my soul to You, and I have turned my face towards You, and I have entrusted my affairs to You, and I have turned my back towards You, desiring You and fearing You, and there is no refuge and no escape from You except towards You. I believe in Your Book which You have revealed, and I believe in Your Prophet whom You have sent. Then if you die that night, you will die upon the natural faith.
