It is narrated from a Companion (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Soon Syria will be conquered at your hands. When you are given the choice to settle at any place there, choose the city called "Damascus," for it will be the best refuge for Muslims in times of war.
