Kurkir then had their heads sent to 'Adud al-Dawla, who was Shiraz.^[2] However, the natives of Kirman continued to resist Kurkir, who was shortly reinforced by an army under 'Abid ibn 'Ali.

They then marched towards Jiroft, and fought the rebels on December 13, which resulted in victory for the Buyids, and the death of several leading figures of the rebellion.^[3] In 972, Kurkir, who had offended 'Adud al-Dawla, shortly fell out of favor, and was imprisoned in Siraf.
