This is a fundamental principle of classical logic (specifically, the principle of explosion or ex falso quodlibet, which dictates that any conclusion follows from a contradictory set of premises), making citation unnecessary.
The claim addresses a well-established property of formal deductive logic where a contradictory (unsatisfiable) premise set entails every proposition, rendering the argument vacuously valid. This is a matter of formal logic definitions taught in introductory philosophy and mathematics, classifying it as common knowledge within the domain.
