The Prophet (ﷺ) said, "Nobody who dies and finds good from Allah (in the
Hereafter) would wish to come back to this world even if he were given
the whole world and whatever is in it, except the martyr who, on
seeing the superiority of martyrdom, would like to come back to the
world and get killed again (in Allah's Cause)." - Hadith Al Bukhari 2795 (islam)
