Jarir b. ‘Abdillah told that when God’s Messenger sent an expedition to Khath'am some of them sought God’s protection by having recourse to prostration* and were quickly killed. When the Prophet (ﷺ) heard that, he ordered half the blood wit to be paid for them, saying, “I am not responsible for any Muslim who stays among polytheists.” On being asked why that was, he replied, “Their fires should not be visible to one another.” Abu Dawud transmitted it. * Some members of Khath'am who were Muslims prostrated themselves in prayer to God thinking that this would make it clear to the attackers that they were Muslims.
