Narrated `Abdullah: Allah's Apostle said, "The blood of a Muslim who confesses that none has the right to be worshipped but Allah and that I am His Apostle, cannot be shed except in three cases: In Qisas for murder, a married person who commits illegal sexual intercourse and the one who reverts from Islam (apostate) and leaves the Muslims."

Narrated Abu Qilaba: That he was sitting behind `Umar bin `Abdul `Aziz and the people mentioned and mentioned (about at-Qasama) and they said (various things), and said that the Caliphs had permitted it. `Umar bin `Abdul `Aziz turned towards Abu Qilaba who was behind him and said. "What do you say, O `Abdullah bin Zaid?" or said, "What do you say, O Abu Qilaba?" Abu Qilaba said, "I do not know that killing a person is lawful in Islam except in three cases: a married person committing illegal sexual intercourse, one who has murdered somebody unlawfully, or one who wages war against Allah and His Apostle." 'Anbasa said, "Anas narrated to us such-and-such." Abu Qilaba said, "Anas narrated to me in this concern, saying, some people came to the Prophet and they spoke to him saying, 'The climate of this land does not suit us.' The Prophet said, 'These are camels belonging to us, and they are to be taken out to the pasture. So take them out and drink of their milk and urine.' So they took them and set out and drank of their urine and milk, and having recovered, they attacked the shepherd, killed him and drove away the camels.' Why should there be any delay in punishing them as they murdered (a person) and waged war against Allah and His Apostle and frightened Allah's Messenger ?" Anbasa said, "I testify the uniqueness of Allah!" Abu Qilaba said, "Do you suspect me?" 'Anbasa said, "No, Anas narrated that (Hadith) to us." Then 'Anbasa added, "O the people of such-and-such (country), you will remain in good state as long as Allah keeps this (man) and the like of this (man) amongst you."

Narrated Abu Qilaba: Once `Umar bin `Abdul `Aziz sat on his throne in the courtyard of his house so that the people might gather before him. Then he admitted them and (when they came in), he said, "What do you think of Al-Qasama?" They said, "We say that it is lawful to depend on Al-Qasama in Qisas, as the previous Muslim Caliphs carried out Qisas depending on it." Then he said to me, "O Abu Qilaba! What do you say about it?" He let me appear before the people and I said, "O Chief of the Believers! You have the chiefs of the army staff and the nobles of the Arabs. If fifty of them testified that a married man had committed illegal sexual intercourse in Damascus but they had not seen him (doing so), would you stone him?" He said, "No." I said, "If fifty of them testified that a man had committed theft in Hums, would you cut off his hand though they did not see him?" He replied, "No." I said, "By Allah, Allah's Apostle never killed anyone except in one of the following three situations: (1) A person who killed somebody unjustly, was killed (in Qisas,) (2) a married person who committed illegal sexual intercourse and (3) a man who fought against Allah and His Apostle and deserted Islam and became an apostate." Then the people said, "Didn't Anas bin Malik narrate that Allah's Apostle cut off the hands of the thieves, branded their eyes and then, threw them in the sun?" I said, "I shall tell you the narration of Anas. Anas said: "Eight persons from the tribe of `Ukl came to Allah's Apostle and gave the Pledge of allegiance for Islam (became Muslim). The climate of the place (Medina) did not suit them, so they became sick and complained about that to Allah's Apostle. He said (to them), "Won't you go out with the shepherd of our camels and drink of the camels' milk and urine (as medicine)?" They said, "Yes." So they went out and drank the camels' milk and urine, and after they became healthy, they killed the shepherd of Allah's Apostle and took away all the camels. This news reached Allah's Apostle , so he sent (men) to follow their traces and they were captured and brought (to the Prophet). He then ordered to cut their hands and feet, and their eyes were branded with heated pieces of iron, and then he threw them in the sun till they died." I said, "What can be worse than what those people did? They deserted Islam, committed murder and theft." Then 'Anbasa bin Sa`id said, "By Allah, I never heard a narration like this of today." I said, "O 'Anbasa! You deny my narration?" 'Anbasa said, "No, but you have related the narration in the way it should be related. By Allah, these people are in welfare as long as this Sheikh (Abu Qilaba) is among them." I added, "Indeed in this event there has been a tradition set by Allah's Apostle. The narrator added: Some Ansari people came to the Prophet and discussed some matters with him, a man from amongst them went out and was murdered. Those people went out after him, and behold, their companion was swimming in blood. They returned to Allah's Apostle and said to him, "O Allah's Apostle, we have found our companion who had talked with us and gone out before us, swimming in blood (killed)." Allah's Apostle went out and asked them, "Whom do you suspect or whom do you think has killed him?" They said, "We think that the Jews have killed him." The Prophet sent for the Jews and asked them, "Did you kill this (person)?" They replied, "No." He asked the Al-Ansars, "Do you agree that I let fifty Jews take an oath that they have not killed him?" They said, "It matters little for the Jews to kill us all and then take false oaths." He said, "Then would you like to receive the Diya after fifty of you have taken an oath (that the Jews have killed your man)?" They said, "We will not take the oath." Then the Prophet himself paid them the Diya (Blood-money)." The narrator added, "The tribe of Hudhail repudiated one of their men (for his evil conduct) in the Pre-lslamic period of Ignorance. Then, at a place called Al-Batha' (near Mecca), the man attacked a Yemenite family at night to steal from them, but a. man from the family noticed him and struck him with his sword and killed him. The tribe of Hudhail came and captured the Yemenite and brought him to `Umar during the Hajj season and said, "He has killed our companion." The Yemenite said, "But these people had repudiated him (i.e., their companion)." `Umar said, "Let fifty persons of Hudhail swear that they had not repudiated him." So forty-nine of them took the oath and then a person belonging to them, came from Sham and they requested him to swear similarly, but he paid one-thousand Dirhams instead of taking the oath. They called another man instead of him and the new man shook hands with the brother of the deceased. Some people said, "We and those fifty men who had taken false oaths (Al-Qasama) set out, and when they reached a place called Nakhlah, it started raining so they entered a cave in the mountain, and the cave collapsed on those fifty men who took the false oath, and all of them died except the two persons who had shaken hands with each other. They escaped death but a stone fell on the leg of the brother of the deceased and broke it, whereupon he survived for one year and then died." I further said, "`Abdul Malik bin Marwan sentenced a man to death in Qisas (equality in punishment) for murder, basing his judgment on Al-Qasama, but later on he regretted that judgment and ordered that the names of the fifty persons who had taken the oath (Al-Qasama), be erased from the register, and he exiled them in Sham."
