Allah's Messenger (ﷺ) said, "Allah guarantees him who strives in His Cause and whose motivation for going
out is nothing but Jihad in His Cause and belief in His Word, that He will admit him into Paradise (if
martyred) or bring him back to his dwelling place, whence he has come out, with what he gains of
reward and booty."
Sahih al-Bukhari Book 57, Hadith 32
