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 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.
Abud Darda’ reported God’s Messenger as saying, “He who gets land on which tax is due 1 has sought to rescind his emigration,2 and he who takes an infidel’s lowliness from his neck and puts it on his own 3 has turned his back on Islam.”
Abu Dawud transmitted it.
1. The word for "tax" here is jizya. Eventually a distinction was made between jizya and kharaj, the former being used for poll-tax and the latter for land-tax.
2. i.e. to make himself like a dhimmi.
3. i.e. undertakes the responsibility of paying his tax for him.
