Then he should lie down on his right side, then recite this supplication: My Lord, in Your name I have placed my side, and in Your name I will raise it. So if You take my soul, have mercy on it. And if You leave it alive, protect it with the protection with which You protect Your righteous servants.

There is no refuge and no place of safety from Your grasp except with You. I believe 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.

Allah is pure from all defects and is with His praise, all praise is for Allah alone, there is no deity worthy of worship except Allah, Allah is the Greatest. Then the sins of that person will be forgiven even if they are as much as the foam of the sea.

Hazrat Naufal narrates that the Messenger of Allah, peace and blessings be upon him, said to him: "What has brought you here?" I submitted: "O Messenger of Allah, peace and blessings be upon you! I have come so that you may teach me a supplication to recite at bedtime." The Prophet, peace and blessings be upon him, said: "When you lie down on your bed, recite Surah Al-Kafirun, and after completing it, go to sleep. For this Surah is a declaration of freedom from shirk (associating partners with Allah)."

Hazrat Naufal Ashja'i narrates that I submitted: O Messenger of Allah (peace and blessings be upon him)! Please tell me a supplication which I may recite in the morning and evening.

And when you place the deceased in his grave, recite this supplication at that time as well.

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.
