Why was the 637 siege of Ctesiphon a turning point?

The siege of Ctesiphon took place from January to March 637, following the Rashidun Caliphate's victory at the Battle of al-Qadisiyyah. Capturing the long-standing Sasanian capital consolidated Muslim rule over Mesopotamia and paved the way for further invasions into the Persian mainland. This pivotal campaign fundamentally altered power dynamics in the region under commanders like Sa'd ibn Abi Waqqas.
