What is the meaning of the phrase "Do not abandon me to myself for the blink of an eye" which is found in the supplications of the Messenger of Allah, peace and blessings be upon him?

The author of Awn al-Ma'bud stated that the meaning of "la takilni" (لا تكلني) is "do not leave me," and "tarfat 'ayn" (طرفة عين) means a moment or a glance of an eye. The author of Lisan al-ʿArab mentioned that "wakaltu amri ila fulan" (وكلت أمري إلى فلان) means "I entrusted my matter to so-and-so," and that a man's agent (wakil) is so named because his principal (muwakkil) entrusted him with carrying out his affairs. In Mukhtar al-Sihah, "tarfah" (طرفة) refers to a single instance of a glance.
