What is the ruling on one who reads the word "wal-Nabi" (By the Prophet), which contains the vocative waw of oath and swearing by other than Allah, if the video title begins with it?

It is not permissible to swear by the Prophet, peace and blessings be upon him, or by any other created being. One who recites an oath by the Prophet, peace and blessings be upon him, as a narration for a video or otherwise, is not considered to have sworn by him. Just as the one who transmits or narrates disbelief is not a disbeliever, so too the one who narrates an oath by a created being is not considered to have sworn by it.
