وَعَرَفَاتُ كُلُّهَا مَوْقِفٌ إِلَّا بَطْنَ عُرَنَةَ.
Translation: All of Arafat is a valid place of standing except the valley floor of Uranah.
The word kulluhā includes every valid part of Arafat. Batn ʿUranah is specifically excluded, so being inside the recognized Arafat boundary is important.
Closeness to the mountain is not a condition. In contemporary settings, the officially marked boundaries—not just a road or building name—must be respected.
