Hazrat Asim narrates that Hazrat Ali (may Allah be pleased with him) said: When you lie down on your bed, recite this supplication: In the name of Allah, and in the way of Allah, and upon the religion of the Messenger of Allah (peace and blessings be upon him). And when you place the deceased in his grave, recite this supplication at that time as well.

Hazrat Bara bin Azib narrates that the Messenger of Allah, peace and blessings be upon him, said to a companion: O so-and-so! When you lie down on your bed, recite this supplication: O Allah! I have surrendered my soul to You, and I have turned my face towards You, and I have entrusted my affairs to You. There is no refuge and no place of safety from Your punishment except with Your mercy. I have believed in the Book which You have revealed and in the Prophet whom You have sent. The Prophet, peace and blessings be upon him, said: If you die that night, you will die upon the natural faith of Islam, and if you reach the morning, you will attain goodness.

Hazrat Abdullah bin Amr (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) asked an Ansari companion: "When you intend to sleep, what supplication do you recite?"
