وَإِنْ قَدَرَ عَلَى إِدْرَاكِ الْحَجِّ، دُونَ الْهَدْيِ: جَازَ لَهُ التَّحَلُّلُ؛ اسْتِحْسَانًا.
Translation: If Hajj is still reachable but the dispatched offering cannot be reached, release is permitted by juristic preference (istihsan).
This is the third case: Hajj is reachable, but the dispatched offering cannot be intercepted or reached. Al-Quduri states that release is allowed by istihsan.
Istihsan is a juristic method of reasoning, not a casual personal preference. This does not nullify the obligation to continue when both Hajj and offering are reachable.
