How authentic is this Hadith: "Whoever is content with My decree, I will give him according to My measure"?

This hadith (definition) does not exist in the authentic books of Sunnah (definition), and it appears to be an invented fabrication against the Prophet, peace and blessings be upon him. It is not permissible to circulate or publish it, except to demonstrate its inauthenticity, due to the Prophet's saying: "Indeed, lying about me is not like lying about anyone else. Whoever intentionally lies about me, let him take his seat in the Fire," and "Do not lie about me, for whoever lies about me shall enter the Fire," and "Whoever narrates a hadith from me which he considers to be a lie, then he is one of the liars."
