‘Ubada b. as-Samit reported God’s Messenger as saying, “He who fights in God’s path with no intention but getting a tethering rope will have what he intended.”* * This saying advocates the necessity of having proper motives. If all one wants is some material gain that is all he will get, for he will not deserve any eternal reward. Nasa’i transmitted it.
