United under Kubrat of the Dulo clan (identical to the ruler mentioned by Persian chronicler Tabari under the name of Shahriar), the joined forces of the Utigur and Kutrigur Bulgars, and probably the Bulgar Onogurs, broke loose from the Turkic khanate in the 630s.
The town is mentioned in Tabari's history from the 10th century, when it was an important stop on the northern branch of the Silk Road.
The place the arrow landed is variously identified as 'Mount Khvanvant' in the Avesta (likewise an unknown location); a river in Balkh (Tabari, al-Atir); east of Balkh (Talebi); Bactria/Tokharistan (Maqdesi, Gardizi); the banks of the Oxus River (Balami) or Merv (Mojmal).
Some early Islamic histories recount that as Muhammad was reciting Sūra Al-Najm (Q.53), as revealed to him by the angel Gabriel, Satan tempted him to utter the following lines after verses 19 and 20: "Have you thought of Al-lāt and al-'Uzzā and Manāt the third, the other; These are the exalted Gharaniq, whose intercession is hoped for."
The event is also mentioned by the Muslim scholars Ibn Hisham, Waqidi and Tabari.
