Could you please clarify all types of Tawaf in Hajj and Umrah?

For 'Umrah, there is one Tawaf, which is a pillar.

For Hajj, there are three types of Tawaf: 1. Tawaf al-Qudum (Tawaf of Arrival): It is a Sunnah according to the majority of scholars, and nothing is required if it is omitted. However, it is obligatory according to the Malikis, and its omission necessitates a sacrifice (dam). 2. Tawaf al-Ifadah (Tawaf of Overflowing, also known as Tawaf al-Ziyarah or Tawaf al-Hajj): This is a pillar of Hajj and is required of all pilgrims. 3. Tawaf al-Wada' (Farewell Tawaf): It is obligatory according to the majority of scholars, and its omission necessitates a sacrifice (dam), except for a menstruating woman. It is considered a Sunnah by the Malikis and by one opinion within the Shafi'i school.

Additionally, there is Tawaf al-Tatawwu' (voluntary Tawaf) for any pilgrim who wishes to perform it.
