روز عرفه, or the Day of Arafah, is the second day of the Islamic pilgrimage, known as Hajj. It falls on the 9th day of the Islamic month of Dhu al-Hijjah. This day is significant for Muslims as it commemorates the day when the Prophet Muhammad delivered his final sermon, emphasizing the importance of faith and unity. On this day, pilgrims gather at the plain of Arafat to pray and seek forgiveness. It is also a time for reflection and supplication for all Muslims, even those not performing Hajj. The day concludes with the celebration of Eid al-Adha, which follows the Hajj rituals.
