"Al-Multan was named ‘Frontier-place of the House of Gold’ (Farj Bayt al-Dhahab), because Muhammad b. al-Qasim, the lieutenant of Hajjaj b. Yusuf, had obtained forty bhar of gold from a house there. One bhar is equal to three hundred and thirty-three mann. It was for this reason that the town was named ‘Frontier-place of the House of Gold’. [The word] al-farj is synonymous with al-thaghr [frontier]. The quantity of the gold obtained was 2,37,600 mithqal…From al-Sind costus, qana and al-khayzuran (bamboos) are imported."
