At Arafat during Hajj, the rite called “standing before God” is known as wuquf.
Wuquf, also transliterated الوقوف and sometimes written wuqūf, is the central vigil at the Plain of Arafat. On 9 Dhu al-Hijjah, pilgrims travel from Mina to Arafat, where they remain from after midday until sunset making supplications, repenting and listening to the sermon.
The rite is so essential that missing the prescribed period at Arafat is traditionally regarded as invalidating the Hajj. This gives the Day of Arafah, the ninth day of Dhu al-Hijjah, a special place in the pilgrimage and in the Islamic calendar. Eid al-Adha begins the following day.
The alternative answers name other Hajj rites. Tawaf is circumambulation of the Kaaba, sa'i is walking between Safa and Marwa, and ramy refers to throwing pebbles at the pillars in Mina. Wuquf is specifically the standing vigil at Arafat, not a movement between sacred sites.
