The Prophet (saws) prohibited to kill four creatures: ants, bees, hoopoes, and sparrow-hawks.

When it was the day of (the battle of) Hunain, I saw a Muslim man fighting with one of the pagans and another pagan was hiding himself behind the Muslim in order to kill him. So I hurried towards the pagan who was hiding behind the Muslim to kill him, and he raised his hand to hit me but I hit his hand and cut it off. That man got hold of me and pressed me so hard that I was afraid (that I would die), then he knelt down and his grip became loose and I pushed him and killed him. The Muslims (excepting the Prophet and some of his companions) started fleeing and I too, fled with them. Suddenly I met `Umar bin Al-Khattab amongst the people and I asked him, "What is wrong with the people?" He said, "It is the order of Allah" Then the people returned to Allah's Apostle (after defeating the enemy). Allah's Apostle said, "Whoever produces a proof that he has killed an infidel, will have the spoils of the killed man." So I got up to look for an evidence to prove that I had killed an infidel, but I could not find anyone to bear witness for me, so I sat down. Then it came to my mind (that I should speak of it) and I mentioned the case to Allah's Apostle. A man from the persons who were sitting with him (i.e. the Prophet), said, "The arms of the deceased one whom he ( i.e. Abu Qatada) has mentioned, are with me, so please compensate him for it (i.e. the spoils)," Abu Bakr said, "No, Allah's Apostle will not give it (i.e. the spoils) to a weak humble person from Quraish and leave one of Allah's Lions who fights on behalf of Allah and His Apostle." Allah's Apostle then got up and gave that (spoils) to me, and I bought with it, a garden which was the first property I got after embracing Islam.

The Prophet said, "Who is ready to kill Ka`b bin Al-Ashraf who has really hurt Allah and His Apostle?" Muhammad bin Maslama said, "O Allah's Apostle! Do you like me to kill him?" He replied in the affirmative. So, Muhammad bin Maslama went to him (i.e. Ka`b) and said, "This person (i.e. the Prophet) has put us to task and asked us for charity." Ka`b replied, "By Allah, you will get tired of him." Muhammad said to him, "We have followed him, so we dislike to leave him till we see the end of his affair." Muhammad bin Maslama went on talking to him in this way till he got the chance to kill him.

The Prophet said, "Who will go and see what has happened to Abu Jahl?" Ibn Mas`ud went and found that the two sons of 'Afra had struck him fatally (and he was in his last breaths). `Abdullah bin Mas`ud said, "Are you Abu Jahl?" And took him by the beard. Abu Jahl said, "Can there be a man superior to one you have killed or one whom his own folk have killed?"

When the Prophet went out for (the battle of) Uhud, some of his companions (hypocrites) returned (home). A party of the believers remarked that they would kill those (hypocrites) who had returned, but another party said that they would not kill them. So, this Divine Inspiration was revealed: "Then what is the matter with you that you are divided into two parties concerning the hypocrites." (4.88) The Prophet said, "Medina expels the bad persons from it, as fire expels the impurities of iron."

The Prophet (saws) said: Eat what ever is caught for you by a dog or a hawk you have trained and set off when you have mentioned Allah's name. I said: (Does this apply) if it killed (the animal)? He said: When it kills it without eating any of it, for it caught it only for you.

Abu Dawud said: If a hawk eats any of it, there is no harm (in eating it). If a dog eats it, it is disapproved (to eat the meat). If it drinks blood, there is no harm (in eating it).

When this verse was revealed: "If they do come to thee, either judge between them, or decline to interfere....If thou judge, judge in equity between them." Banu an-Nadir used to pay half blood-money if they killed any-one from Banu Qurayzah. When Banu Qurayzah killed anyone from Banu an-Nadir, they would pay full blood-money. So the Messenger of Allah (saws) made it equal between them.

One of the two women of Hudhayl killed the other, Each of them had husband and sons. The Messenger of Allah (saws) fixed the blood-wit for the slain woman to be paid by the woman's relatives on the father's side. He declared her husband and the child innocent. The relatives of the woman who killed said: We shall inherit from her. The Messenger of Allah (saws) said: No, her sons and her husband should inherit from her.

Allah's Apostle called the salamander a bad animal, but I did not hear him ordering it to be killed."

Ibn 'Umar (Allah be pleased with them) reported Allah's Messenger (may peace be upon him) giving command for killing dogs.

At the battle of Badr the Messenger of Allah gave me AbuJahl's sword, as I had killed him.

The Prophet (saws) said: I will not forgive anyone who kills after accepting blood-wit

Yahya related to me from Malik that Rabia ibn Abi Abd ar-Rahman said, "The slave of fair complexion and excellence is estimated at fifty dinars or six hundred dirhams. The blood-money of a free muslim woman is five hundred dinars or six thousand dirhams."

Malik said, "The blood-money of the foetus of a free woman is a tenth of her blood-money. The tenth is fifty dinars or six hundred dirhams."

Malik said, "I have not heard anyone dispute that there is no slave in compensation for the foetus until it leaves its mother's womb and falls still-born from her womb . "

Malik said, "I heard that if the foetus comes out of its mother's womb alive and then dies, the full blood-money is due for it."

Malik said, "The foetus is not alive unless it cries at birth. If it comes out of its mother's womb and cries out and then dies, the complete blood-money is due for it. We think that the slave- girl's foetus has a tenth of the price of the slave-girl."

Malik said, "When a woman murders a man or woman, and the murderess is pregnant, retaliation is not taken against her until she has given birth. If a woman who is pregnant is killed intentionally or unintentionally, the one who killed her is not obliged to pay anything for her foetus. If she is murdered, then the one who killed her is killed and there is no blood-money for her foetus. If she is killed accidentally, the tribe obliged to pay on behalf of her killer pays her blood-money, and there is no blood-money for the foetus."

Yahya related to me, "Malik was asked about the foetus of the christian or jewish woman which was aborted. He said, 'I think that there is a tenth of the blood-money of the mother for it.' "

The Prophet ordered that a short-tailed or mutilated-tailed snake (i.e. Abtar) should be killed, for it blinds the on-looker and causes abortion."

'Abdullah reported that Allah's Messenger (may peace be upon him) commanded a Muhrim (one who is in the state of pilgrimage) to kill the snake at Mina.

The Prophet (saws) said: He who has been appointed a judge has been killed without a knife.

The Prophet (saws) said: Kill all the snakes, and he who fears their revenge does not belong to me.

11 Malik related to me from Yahya ibn Said from Urwa ibn az- Zubayr that a man of the Ansar called Uhayha ibn al-Julah had a young paternal uncle who was younger than him and who was living with his maternal uncles. Uhayha took him and killed him. His maternal uncles said, "We brought him up from a baby to a youth till he stood firm on his feet, and we have had the right of a man taken from us by his paternal uncle." Urwa said, "For that reason a killer does not inherit from the one he killed."

Malik said, "The way of doing things about which there is no dispute is that the intentional murderer does not inherit anything of the blood-money of the person he has murdered or any of his property. He does not stop anyone who has a share of inheritance from inheriting. The one who kills accidentally does not inherit anything of the blood-money and there is dispute as to whether or not he inherits from the dead person's property because there is no suspicion that he killed him for his inheritance and in order to take his property. I prefer that he inherit from the dead person's property and not inherit from the blood-money."

Yahya related to me from Malik from Hisham ibn Urwa that his father used to kill his sacrificial animals while they were standing.

Malik said, "No-one is permitted to shave his head until he has killed his sacrificial animal, and no-one must sacrifice before dawn on the day of sacrifice. The things that should be done on the day of sacrifice are slaughtering, donning clothes, grooming the body generally (at-tafath) and shaving the head, and none of this may be done before the day of sacrifice."

A Jew killed a girl so that he may steal her ornaments. He struck her with a stone, and she was brought to the Prophet while she was still alive. The Prophet asked her, "Did such-and-such person strike you?" She gestured with her head, expressing denial. He asked her for the second time, and she again gestured with her head, expressing denial. When he asked her for the third time, she beckoned, "Yes." So the Prophet killed him (the Jew) with two stones.

The pagans were defeated on the day (of the battle) of Uhud. Satan shouted among the people on the day of Uhud, "O Allah's worshippers! Beware of what is behind you!" So the front file of the army attacked the back files (mistaking them for the enemy) till they killed Al-Yaman. Hudhaifa (bin Al- Yaman) shouted, "My father!" My father! But they killed him. Hudhaifa said, "May Allah forgive you." (The narrator added: Some of the defeated pagans fled till they reached Taif.)

For thirty days Allah's Apostle invoked Allah to curse those who had killed the companions of Bir- Mauna; he invoked evil upon the tribes of Ral, Dhakwan, and Usaiya who disobeyed Allah and His Apostle. There was reveled about those who were killed at Bir-Mauna a Qur'anic Verse we used to recite, but it was cancelled later on. The Verse was: "Inform our people that we have met our Lord. He is pleased with us and He has made us pleased."

When we were with the Messenger of Allah (saws) on an expedition, he saw some people collected together over something and sent a man and said: See, what are these people collected around? He then came and said: They are round a woman who has been killed. He said: This is not one with whom fighting should have taken place. Khalid ibn al-Walid was in charge of the van; so he sent a man and said: Tell Khalid not to kill a woman or a hired servant.

The Messenger of Allah (saws) Said: The blood of a Muslim man who testifies that there is no god but Allah and that Muhammad is Allah's Apostle should not lawfully be shed except only for one of three reasons: a man who committed fornication after marriage, in which case he should be stoned; one who goes forth to fight with Allah and His Apostle, in which case he should be killed or crucified or exiled from the land; or one who commits murder for which he is killed.

He also said, "If people knew what there was in the call to prayer and the first row, and they could find no other way except to draw lots for it, they would draw lots for it. And if they knew what there was in doing dhuhr at its time, they would race each other to it. And if they knew what there was in the prayers of isha and maghrib, they would come to them even if they had to crawl .

One day Allah's Apostle narrated to us a long narration about Ad-Dajjal and among the things he narrated to us, was: "Ad-Dajjal will come, and he will be forbidden to enter the mountain passes of Medina. He will encamp in one of the salt areas neighboring Medina and there will appear to him a man who will be the best or one of the best of the people. He will say 'I testify that you are Ad-Dajjal whose story Allah's Apostle has told us.' Ad-Dajjal will say (to his audience), 'Look, if I kill this man and then give him life, will you have any doubt about my claim?' They will reply, 'No,' Then Ad- Dajjal will kill that man and then will make him alive. The man will say, 'By Allah, now I recognize you more than ever!' Ad-Dajjal will then try to kill him (again) but he will not be given the power to do so."

Allah's Apostle told us a long narrative about Ad-Dajjal, and among the many things he mentioned, was his saying, "Ad-Dajjal will come and it will be forbidden for him to pass through the entrances of Medina. He will land in some of the salty barren areas (outside) Medina; on that day the best man or one of the best men will come up to him and say, 'I testify that you are the same Dajjal whose description was given to us by Allah's Apostle .' Ad-Dajjal will say to the people, 'If I kill this man and bring him back to life again, will you doubt my claim?' They will say, 'No.' Then Ad-Dajjal will kill that man and bring him back to life. That man will say, 'Now I know your reality better than before.' Ad-Dajjal will say, 'I want to kill him but I cannot.' "

Allah's Apostle said, "A faithful believer remains at liberty regarding his religion unless he kills somebody unlawfully."

One of the evil deeds with bad consequence from which there is no escape for the one who is involved in it is to kill someone unlawfully.
