Hazrat Bara’ narrates that the Messenger of Allah, peace and blessings be upon him, said to a man: O so-and-so! When you lie down on your bed, say these words:“O Allah! I have submitted my soul to You, and I have turned my back towards You.”Then he mentioned the same content as before, but also said: So if you die that night, your death will be upon the natural disposition (fitrah), and if you reach the morning, then you will attain goodness.
