Allâh's Messenger (ﷺ) said, "To guard Muslims from infidels in Allâh's Cause for one day is better than the world and whatever is on its surface, and a place in Paradise as small as that occupied by the whip of one of you is better than the world and whatever is on its surface; and a morning's or an evening's journey which a slave (person) travels in Allâh's Cause is better than the world and whatever is on its surface." [4:142-O.B]
