question #1 Sahih al-Bukhari 2803, Book 56, Hadith 20 : What is the significance of being wounded in the cause of Allah according to Islamic teachings?

Allah’s Messenger (ﷺ) said, “By Him in Whose Hands my soul is! Whoever is wounded in Allah’s
Cause….and Allah knows well who gets wounded in His Cause….will come on the Day of
Resurrection with his wound having the color of blood but the scent of musk.”
