Umrah, derived from the word 'umrah,' means 'to visit' or 'to perform a pilgrimage.' In practice, it does not involve staying overnight in Arafah, Muzdalifah, and Mina. Instead, Umrah is a visit to the Kaaba to perform a few acts of worship.
The duration of Umrah is also shorter, unlike the Hajj pilgrimage. Umrah can be performed at any time, except on the days of Arafah, Nahr, and Tashriq
