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.
Ibn Abu Laila said he was told by Muhammad’s companions that during a journey with God’s Messenger while one of them was asleep another went to a rope he had with him and seized him,* with the result that he was startled. God’s Messenger then said, “It is not lawful for a Muslim to frighten another.”
Abu Dawud transmitted it.
* The meaning is that he tied the rope round him while he was asleep, presumably as a joke.
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.
Narrated A’isha reported God’s Messenger as saying, “The blood of a Muslim man who testifies that there is no god but God and that Muhammad is God’s Messenger may lawfully be shed only for one of three reasons:
fornication after marriage, in which case he should be stoned; one who goes forth to fight with God and His Messenger,* in which case he should be killed, or crucified, or made a fugitive; or one which commits murder for which he is killed.”
Abu Dawud transmitted it.
* Mirqat iv. 53 refers this to such things as highway robbery.
