Quotes

 * “Thus if [a] Muslim commits adultery his punishment is 100 lashes, the shaving of his head, and one year of banishment. But if the man is not a Muslim and commits adultery with a Muslim woman his penalty is execution. … Similarly if a Muslim deliberately murders another Muslim he falls under the law of retaliation and must by law be put to death by the next of kin. But if a non-Muslim who dies at the hand of a Muslim has by lifelong habit been a non-Muslim, the penalty of death is not valid. Instead the Muslim murderer must pay a fine and be punished with the lash. … Since Islam regards non-Muslims as on a lower level of belief and conviction, if a Muslim kills a non-Muslim, then his punishment must not be the retaliatory death, since the faith and conviction he possesses is loftier than that of the man slain…Again, the penalties of a non-Muslim guilty of fornication with a Muslim woman are augmented because, in addition to the crime against morality, social duty and religion, he has committed sacrilege, in that he has disgraced a Muslim and thereby cast scorn upon the Muslims in general, and so must be executed. … Islam and its peoples must be above the infidels, and never permit non-Muslims to acquire lordship over them.” —

Quotes from Hadith

 * Narrated Ikrima: Ali burnt some people and this news reached Ibn 'Abbas, who said, "Had I been in his place I would not have burnt them, as the Prophet said, 'Don't punish (anybody) with Allah's Punishment.' No doubt, I would have killed them, for the Prophet said, 'If somebody (a Muslim) discards his religion, kill him.' "
 * Sahih Bukhari 4:52:260
 * Narrated 'Ikrima: Some Zanadiqa (atheists) were brought to 'Ali and he burnt them. The news of this event, reached Ibn 'Abbas who said, "If I had been in his place, I would not have burnt them, as Allah's Apostle forbade it, saying, 'Do not punish anybody with Allah's punishment (fire).' I would have killed them according to the statement of Allah's Apostle, 'Whoever changed his Islamic religion, then kill him.'"

 * 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."
 * Sahih Bukhari 9:83:17
 * 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."...
 * Sahih Bukhari 9:83:37
 * Narrated 'Ali: I relate the traditions of Allah's Apostle to you for I would rather fall from the sky than attribute something to him falsely. But when I tell you a thing which is between you and me, then no doubt, war is guile. I heard Allah's Apostle saying, "In the last days of this world there will appear some young foolish people who will use (in their claim) the best speech of all people (i.e. the Qur'an) and they will abandon Islam as an arrow going through the game. Their belief will not go beyond their throats (i.e. they will have practically no belief), so wherever you meet them, kill them, for he who kills them shall get a reward on the Day of Resurrection."
 * Sahih Bukhari 4:56:808, See Also Sahih Bukhari 6:61:577
 * Narrated Uthman ibn Affan: AbuUmamah ibn Sahl said: We were with Uthman when he was besieged in the house. There was an entrance to the house. He who entered it heard the speech of those who were in the Bilat. Uthman then entered it. He came out to us, looking pale. He said: They are threatening to kill me now. We said: Allah will be sufficient for you against them, Commander of the Faithful! He asked: Why kill me? I heard the Apostle of Allah (peace be upon him) say: It is not lawful to kill a man who is a Muslim except for one of the three reasons: Kufr (disbelief) after accepting Islam, fornication after marriage, or wrongfully killing someone, for which he may be killed. I swear by Allah, I have not committed fornication before or after the coming of Islam, nor did I ever want another religion for me instead of my religion since Allah gave guidance to me, nor have I killed anyone. So for what reason do you want to kill me?

 * Narrated Abu Burda:That the Prophet sent his (i.e. Abu Burda's) grandfather, Abu Musa and Mu'adh to Yemen and said to both of them "Facilitate things for the people (Be kind and lenient) and do not make things difficult (for people), and give them good tidings, and do not repulse them and both of you should obey each other." Abu Musa said, "O Allah's Prophet! In our land there is an alcoholic drink (prepared) from barley called Al-Mizr, and another (prepared) from honey, called Al-Bit"' The Prophet said, "All intoxicants are prohibited." Then both of them proceeded and Mu'adh asked Abu Musa, "How do you recite the Quran?" Abu Musa replied, "I recite it while I am standing, sitting or riding my riding animals, at intervals and piecemeal." Muadh said, "But I sleep and then get up. I sleep and hope for Allah's Reward for my sleep as I seek His Reward for my night prayer." Then he (i.e. Muadh) pitched a tent and they started visiting each other. Once Muadh paid a visit to Abu Musa and saw a chained man. Muadh asked, "What is this?" Abu Musa said, "(He was) a Jew who embraced Islam and has now turned apostate." Muadh said, "I will surely chop off his neck!"

 * Narrated Abdullah Ibn Abbas: A blind man had a slave-mother who used to abuse the Prophet (peace be upon him) and disparage him. He forbade her but she did not stop. He rebuked her but she did not give up her habit. One night she began to slander the Prophet (peace be upon him) and abuse him. So he took a dagger, placed it on her belly, pressed it, and killed her. A child who came between her legs was smeared with the blood that was there. When the morning came, the Prophet (peace be upon him) was informed about it. He assembled the people and said: I adjure by Allah the man who has done this action and I adjure him by my right to him that he should stand up. Jumping over the necks of the people and trembling the man stood up. He sat before the Prophet (peace be upon him) and said: Apostle of Allah! I am her master; she used to abuse you and disparage you. I forbade her, but she did not stop, and I rebuked her, but she did not abandon her habit. I have two sons like pearls from her, and she was my companion. Last night she began to abuse and disparage you. So I took a dagger, put it on her belly and pressed it till I killed her. Thereupon the Prophet (peace be upon him) said: Oh be witness, no retaliation is payable for her blood.
 * Sunan Abu Dawud 38:4348


 * 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."...
