There is an open ground three miles to the east of Mecca called Mina. There are three stone pillars in this ground that are called Jumrat representing Satan. These stones are called Jumrah-tul-Oola, Jumrah-tul-Wusta, and Jumrah-tul-Aqbah. During the last day of Hajj, the 10th Dul-Hajj and three Tashriq days, pilgrims are required to cast stones at these Jumrah. This act of casting stones at Jumrah is called Ramy al-jimar (throwing small stones). Thousands of animals are sacrificed on this ground to commemorate the great sacrifice of Hadrat Ibrahim and Hadrat Ishmael.
