At Arafat's edge stands Namirah, where the Prophet ﷺ delivered the comprehensive Farewell Sermon and joined the two noon prayers — a Sunnah alive: among the world's largest mosques (~350,000), its Arafat-day sermon translated to the world. Its front section lies outside Arafat's bounds (signed — precise fiqh pilgrims know); the rest of the year it stands as solemn witness beside Mount Mercy.
