More than two million pilgrims from around the world have converged in Mina to perform the main ritual of Hajj on Monday.
The pilgrims will move to Arafat today, where they will listen to a sermon delivered at Namira Mosque. They will then perform Zuhr and Asr prayers combined.
The pilgrims will spend time in Arafat with prayers for acceptance of their pilgrimage and recitation of Quranic verses until sunset.
After sunset, they will head to Muzdalifah, where they will stay until midnight, engaged in prayers after performing Maghreb and Isha prayers combined.
Tens of thousands of security personnel have been deployed for the pilgrimage.
The interior ministry said on Saturday that the number of pilgrims arriving in Mecca had already surpassed the two million mark, mostly from abroad including large contingents from Egypt, India, Pakistan and Bangladesh.
