وَهَذَا الطَّوَافُ هُوَ الْمَفْرُوضُ فِي الْحَجِّ.
Translation: And this is the tawaf that is obligatory as an integral part of Hajj.
This is the central legal classification in Al-Quduri's passage: Tawaf al-Ziyarah is a farḍ/integral obligation of Hajj. It must not be confused with the Sunnah arrival tawaf or the wajib farewell tawaf.
Simply performing another tawaf does not automatically discharge this integral. Its proper identification and performance are essential to completion of Hajj.
