On the 12th Dhul Hijjah, pilgrims have a choice.
After stoning the Jamarat, they can either choose to remain in Mina for one more night, or they can leave Mina (on the condition that they leave before Maghrib).
It is usually very packed on the 12th because many people want to leave before Maghrib.(NOTE: If you want to build a strong and powerful relationship with Allah, check out Islamia TV, where you can watch Islamic speakers from across the globe deliver inspiring and motivational courses.
