وَالْمُزْدَلِفَةُ كُلُّهَا مَوْقِفٌ إِلَّا بَطْنَ مُحَسِّرٍ.
Translation: All of Muzdalifah is a valid standing place except the valley floor of Muhassir.
This clause limits a possible misunderstanding about stopping near Quzah: a pilgrim need not stand at that mountain. Presence in any valid part of Muzdalifah qualifies.
Batn Muhassir is excluded from the valid standing area. Pilgrims should rely on trustworthy current boundary markings rather than the name of a road or landmark alone.
