Is the soundness of a person's religiosity measured by the light that appears on their face?

The effects of faith and obedience appear on the face of a believer, such as humility, radiance, and good demeanor. Ibn Kathir said in his interpretation of the verse {Their mark is on their faces from the trace of prostration} that a believer's sound inner self with Allah rectifies his outward appearance. Statements from the Salaf confirm this, such as Umar's saying, "Whoever rectifies his inner self, Allah will rectify his outer self," and Ibn Umar's saying, "Indeed, a good deed brings light to the face and نور (light) to the heart." Nevertheless, apparent humility is not conclusive proof of faith, as some may feign it, as Allah mentioned in the Quran {Some faces, that Day, will be humbled Toiling, weary They will enter a blazing fire}. A Muslim should not judge people based solely on these outward appearances.
