One of the following is not required in Umrah?

Arafat is not required in Umrah. Umrah is a pilgrimage to Makkah that can be performed at any time of the year, unlike Hajj which has specific dates. Umrah involves certain rituals such as Ihram (the state of sanctity), Tawaf (circling the Kaaba seven times), Sa'y (walking between the hills of Safa and Marwa seven times), and shaving or trimming the hair. Arafat is a location outside Makkah that is only visited during Hajj, on the 9th of Dhul Hijjah. During Hajj, pilgrims spend the day at Arafat to perform a special prayer and make supplications to Allah. Therefore, Arafat is not required in Umrah.
