I want to know the answer to the following question:
In what period did Islamic armies conquer Syria?
All the background I'm provided with is that "After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634–635 and reaching Egypt in 640–641, Persia between 637 and 642, North Africa in the later 7th century, and the Iberian Peninsula in 711.". Is that enough to answer the question?
Answer: yes
