“People utter three statements that they have incorporated in their life:
they say that they are Allah’s slaves, yet they work as free men do. This contradicts their statement.
They say that Allah provides them with sustenance, yet their hearts are never content except by collecting the traits of this life and earning its splendor. This contradicts their statement.
They say that there is no escaping death, yet they work as if they will never die. This contradicts their statement.” Mukaashafatul-Qulub, p.35
