Mishkat al-Masabih #3683

Mu'adh reported God’s Messenger as saying, “Fighting is of two kinds. The one who seeks God’s favour, obeys the leader, gives property he values, helps his associate and avoids doing mischief will have a reward for all the time he is asleep and awake, but the one who fights in a boasting spirit, for the sake of display and to gain a reputation, who disobeys the leader and does mischief in the earth will not return without credit or blame.’’* * i.e. the wrong he has done exceeds the good. Malik, Abu Dawud and Nasa’i transmitted it.
