Muwatta Imam Malik Book of Hajj, Hadith 175

Yahya related to me from Malik that he had heard that the Messenger of Allah ﷺ said, "The whole of Arafa is a mawqif, except the middle of Urana, and the whole of Muzdalifa is a standing-place, except for the middle of Muhassir."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " عَرَفَةُ كُلُّهَا مَوْقِفٌ وَارْتَفِعُوا عَنْ بَطْنِ عُرَنَةَ وَالْمُزْدَلِفَةُ كُلُّهَا مَوْقِفٌ وَارْتَفِعُوا عَنْ بَطْنِ مُحَسِّرٍ " .
