What is the degree of authenticity of the hadith: "Whatever is decreed for your molars to chew, let them chew"?

The aforementioned statement, "Whatever is destined for your jaws to chew, they will inevitably chew, so chew it, woe unto you, with dignity, and do not chew it with humiliation," is not narrated from the Prophet, peace and blessings be upon him, nor has any scholar attributed it to him. Rather, some Sufi writers have attributed it to some shaykhs without naming them. Its meaning is sound, for whatever Allah has decreed for a servant, he will surely experience. Several authentic hadiths have been narrated concerning this meaning, including the well-known hadith of Ibn Abbas, and the hadith of Abdullah ibn Mas'ud about the soul receiving its full provision. In conclusion, the statement was not narrated from the Prophet, peace and blessings be upon him, nor from any of his companions.
