The Mīqāt Dhu al-Ḥulayfah (Arabic: مِيْقَات ذُو ٱلْحُلَيْفَة‎), also known as Masjid ash-Shajarah (Arabic: مَسْجِد ٱلشَّجَرَة‎, lit. 'Mosque of the Tree') or Masjid Dhu al-Hulayfah (Arabic: مَسْجِد ذُو ٱلْحُلَيْفَة‎), is a mosque in Abyār ʿAlī, Medina, west of Wadi al-'Aqiq, believed by Muslims to be the location where the final Islamic prophet, Muhammad, entered the state of ihram before performing 'Umrah, after the Treaty of Hudaybiyyah. The mosque is located 7 km (4.3 mi) SW of the Al-Masjid an-Nabawi and was defined by Muhammad as the miqat for those willing to perform the Hajj or Umrah pilgrimages from Medina. It is the second-largest miqat mosque after the Miqat Qarn al-Manazil in As-Sayl al-Kabir.
