Remind those of you who are dying of: La ilāha illallāh (There is no god but Allah)

It is recommended to prompt the dying person to say the testimony of faith.
It is disliked to excessively prompt or insist on it once the dying person has said the testimony of faith or understood it, so as not to distress him and cause him to utter something inappropriate.
An-Nawawi said: If the dying person says the testimony of faith once, it should not be repeated for him, except if he speaks something else afterward; then it may be gently prompted again so that the testimony of faith becomes his last words.
The Hadīth emphasizes being present with the dying person to remind him, offer comfort, gently close his eyes, and attend to his rights.
The impermissibility of prompting the deceased (to testify to faith) after death and at the grave after burial, because the Prophet (ﷺ) did not do so.
