The first tawāf which a pilgrim makes when he arrives at Makkah is called tawāf
Answer Details
The first tawāf which a pilgrim makes when he arrives at Makkah is called "al-qudūm". It is the initial tawāf that a pilgrim performs upon arriving in Makkah and it is considered to be one of the most important rituals of Hajj.
During the tawāf, the pilgrim circumambulates the Kaaba seven times in a counterclockwise direction while reciting supplications and prayers. The Kaaba is the black cube-shaped structure located in the center of the Masjid al-Haram, the holiest mosque in Islam.
Performing the tawāf is a symbolic act of unity and devotion to Allah, as well as a recognition of the historical significance of the Kaaba as the first house of worship built by Prophet Ibrahim (Abraham) and his son Isma'il (Ishmael).
In summary, the first tawāf that a pilgrim makes when he arrives at Makkah is called "al-qudūm", and it involves circumambulating the Kaaba seven times in a counterclockwise direction as a symbolic act of unity and devotion to Allah.
