question #1 Sahih al-Bukhari 4309, Book 64, Hadith 340 : What is the significance of Jihad in Islam compared to migration?

I said to Ibn `Umar, “I want to migrate to Sham.” He said, “There is no migration, but Jihad (for
Allah’s Cause). Go and offer yourself for Jihad, and if you find an opportunity for Jihad (stay there)
otherwise, come back.”
