"“He first took Bamian, which he probably reached by way of Herat, and then marched on Balkh where he ruined (the temple) Naushad. On his way back from Balkh he attacked Kabul…“Starting from Panjhir, the place he is known to have visited, he must have passed through the capital city of the Hindu Sahis to rob the sacred temple - the reputed place of coronation of the Sahi rulers-of its sculptural wealth…“The exact details of the spoil collected from the Kabul valley are lacking. The Tarikh [-i-Sistan] records 50 idols of gold and silver and Mas’udi mentions elephants. The wonder excited in Baghdad by elephants and pagan idols forwarded to the Caliph by Ya’qûb also speaks for their high value....“ The best of our authorities put the date of this event in 257 (870-71). Tabari is more precise and says that the idols sent by Ya’qub reached Baghdad in Rabi’ al-Akhar, 257 (Feb.-March, 871). Thus the date of the actual invasion may be placed at the end of AD 870.”"
