Is it true that in the phrase "Lā ʾilāha ʾillā-llāh" (There is no god but Allah), only the lips move, as a facilitation from Allah for the Muslim at the time of death?

The word of Tawhid, "La ilaha illa Allah" (There is no god but Allah), contains no labial letters, and its letters are articulated from the throat and tongue. Some of its letters, such as the hamza and ha, are considered among the most difficult to pronounce. Among the signs of a good ending is for a person's last words to be the Shahada, based on the Prophet's (peace be upon him) saying: "Whoever uttered 'La ilaha illa Allah' as his last words shall enter Paradise." Therefore, scholars have recommended instructing the dying person at the time of death to say the word of Tawhid, as stated in the Hadith: "Instruct your dying ones to say 'La ilaha illa Allah'." The Prophet (peace be upon him) urged Abu Talib and a man from Banu Najjar to say it at their deathbeds.
