What is the ruling on exiting the state of fasting to perform the Hady if the person commenced the fast due to the inability to offer the Hady?

Primary text

Since the person entered the fast due to the lack of the Hady, they are not required to leave the fast for the Hady. This applies similarly to the seven days of fasting. This principle governs the derivation of the original rule upon which the dissenting opinions were analogized concerning what is legislated concerning fasting.
