Tawaf al-Qudum: arrival tawaf; Al-Quduri calls it Sunnah and exempts Makkah residents.
Tawaf al-Ziyarah: the essential Hajj tawaf, covered earlier among the rites of Sacrifice Day.
Tawaf al-Sadr: the obligatory departure-related tawaf, with the exception stated for Makkah residents.
All are seven-circuit tawafs, but their timing, purpose and legal status differ.
