Abu Hanifah: Dam is due in the relevant case when the visitation tawaf is delayed beyond the days of sacrifice.
Abu Yusuf and Muhammad: They do not require a dam merely because of that delay; the tawaf itself must still be performed.
The disagreement concerns compensation for lateness, not whether Tawaf al-Ziyarah is integral to Hajj. This extra detail is taken from Hanafi comparative works including Badaʾiʿ al-Sanaʾiʿ; the cited Al-Quduri clause explicitly names Abu Hanifah.
