Rabinjan or Arbinjan (Arabic: ربنجن، أربنجن) was a medieval town in the region of Transoxiana, between the cities of Samarkand and Bukhara.
It was one of the settlements on the Samarkand-Bukhara road, lying between Zarman to the east and Dabusiyya to the west,[2] and was located to the south of the Sughd River.
During this period there may have been a Christian presence in the town, as evidenced by a ceramic cast for molding crosses which was recovered from the area.
In 699 Habib ibn al-Muhallab undertook a raid against it, but he was opposed by an army led by the lord of Bukhara and decided to withdraw.
Al-Muqaddasi, writing in the late tenth century, recorded that Rabinjan produced a number of goods, including winter shawls, dried dates, metal drinking cups, ropes made of hemp, and sulfur.
