Is the saying "The greatest calamity is the soul's emptiness of the remembrance of my Lord and His light" correct, and what does it mean?

The aforementioned statement does not appear to contain any Sharia prohibitions; rather, its meaning is good. The greatest calamity that can befall a person is a calamity in his religion, by not remembering Allah, who illuminates hearts and heals them. This is in accordance with the words of the Prophet, peace and blessings be upon him: "The example of one who remembers his Lord and one who does not remember his Lord is like that of the living and the dead."
