Persian emperor Yazdegerd III was in no position to set a relief force to Jalula and the fortress surrendered to Muslims seven months later on the terms of annual payment of Jizya (tribute). After capturing Jalula Muslims captured Tikrit and Mosul, completing their conquest of Iraq. After conquest of Iraq (region west of Zagros mountains) Umar decided to consolidate the conquered territory. He apparently for the time being, did not wanted further conquest. He was almost on defensive until the consistent Persian raids in Iraq made him to launch a whole scale invasion of the Persian empire.
