What is recited when instructing the deceased?

The dying person is prompted to utter the words of monotheism (Shahada) when on their deathbed, so it is said to them: "Say: 'La ilaha illallah' (There is no god but Allah)," based on the Hadith: "Prompt your dying ones to say 'La ilaha illallah'." The Prophet, peace and blessings be upon him, said to Abu Talib upon his death: "O uncle, say: 'La ilaha illallah,' a word by which I will bear witness for you before Allah." The intended meaning of "La ilaha illallah" in this Hadith and others is the two declarations of faith (Shahadatayn).
