The ritual of throwing stones on Jumeraat is one of the key practices during the Hajj pilgrimage. It symbolizes the rejection of evil and the temptation faced by Prophet Ibrahim (A.S) when he was tested by Satan.

Muslims perform this ritual in the city of Mina, where there are three stone pillars called Jumeraat. The pilgrims throw small stones at the largest pillar called Jamrah al-Aqaba. This act shows the refusal to obey Satan and a commitment to follow the path of Allah.

The throwing of stones starts on the 11th day of Zulhajj, which is the second day of the main Hajj rituals. Pilgrims collect pebbles from Muzdalfa and then perform the stoning ritual. This day is very important because it marks the beginning of this symbolic rejection of evil.

The ritual continues on the 12th and 13th of Zulhajj as well, but the first day, the 11th, is when the pilgrims start throwing stones for the first time. The 11th Zulhajj is often called the day of "Yawm al-Jumeraat" or the day of stoning.

Understanding the date and significance of the Jumeraat stoning helps Muslims appreciate the deep spiritual meaning behind the Hajj rituals. It reminds them to stay strong against evil and to renew their faith.

This practice is a vital part of Hajj, and knowing when it begins is important for all pilgrims and students of Islamic studies. The 11th Zulhajj is the day when this important ritual officially starts during the pilgrimage.
