The Prophet [SAW] said: "The slain will bring his killer on the Day of Resurrection with his forelock and his head in his hand, and with his jugular veins flowing with blood, and will say: 'O Lord, he killed me,' until he draws near to the Throne." They mentioned repentance to Ibn 'Abbas and he recited this Verse: "And whoever kills a believer intentionally, his recompense is Hell" He said: "It has not been abrogated since it was revealed; there is no way he could repent."

"This Verse - 'And whoever kills a believer intentionally, his recompense is Hell' - was revealed six months after the Verse which was revealed in Surat Al-Furqan."

"And whoever kills a believer intentionally, his recompense is Hell" that he said: "This Verse was revealed eight months after the Verse that is in Tabark Al-Furqan: "And those who invoke not any other ilah (god) along with Allah, or kill such person as Allah has forbidden, except by right."

"I heard Kharijah bin Zaid bin Thabit narrate that his father said: (The Verse) 'And whoever kills a believer intentionally, his recompense is Hell' was revealed and we became worried about it. Then the Verse in Al-Furqan 'And those who invoke not any other ilah (god) along with Allah, or kill such person as Allah has forbidden, except by right.' was revealed."

The Messenger of Allah [SAW] said: "Whoever comes worshipping Allah and not associating anything with Him, establishing Salah, paying Zakah and avoiding major sins, Paradise will be his." They asked him about major sins and he said: "Associating others with Allah, killing a Muslim soul, and fleeing (from the battlefield) on the day of the march."

"I heard Anas say: 'The Messenger of Allah [SAW] said: The major sins are: Associating others with Allah (Shirk), disobeying one's parents, killing a soul (murder) and speaking falsely.'"

The Prophet [SAW] said: "The major sins are: Associating others with Allah, disobeying parents, killing a soul (murder) and swearing a false oath knowingly."

His father - who was one of the Companions of the Prophet [SAW] - told him: "A man said: 'O Messenger of Allah, what are the major sins?' He said: 'They are seven; the most grievous of which are associating others with Allah, killing a soul unlawfully and fleeing (from the battlefield) on the day of the march.'" It is abridged.

"I said: 'O Messenger of Allah, which sin is the most grievous?' He said: 'Setting up a rival to Allah while it is He that has created you.' I said: 'Then what?' He said: 'Killing your child for fear that he may eat with you.' I said: 'Then what?' He said: 'Committing adultery with your neighbor's wife.'"

"I said: 'O Messenger of Allah, which sin is most grievous?' He said: 'Setting up a rival to Allah while it is He that created you.' I said: 'Then what?' He said: 'Killing your child so that he will not eat with you.' I said: 'Then what?' He said: 'Committing adultery with your neighbor's wife.'"

"I asked the Messenger of Allah [SAW], which sin is most grievous?" He said: "Shirk, setting up a rival to Allah, committing adultery with your neighbor's wife, and killing your child for fear of poverty, and that he may eat with you." Then 'Abdullah recited the Verse: "And those who invoke not any other Ilah (god) along with Allah."

"The Messenger of Allah [SAW] said: 'By the One besides Whom there is no other god, it is not permissible to shed the blood of a Muslim who bears witness to La ilaha illalla (there is none worthy of worship except Allah) and that I am the Messenger of Allah, except in three cases: One who leaves Islam and splits away from the Jama'ah, a person who has been married and then commits adultery, and a life for a life.'"

"Aishah said: 'Do you not know that the Messenger of Allah [SAW] said: It is not permissible to shed the blood of a Muslim, except a man who committed adultery after being married, or one who reverted to Kufr after becoming Muslim, or a life for a life.'"

"Aishah said: 'O 'Ammar! Do you not know that it is not permissible to shed the blood of a Muslim except in three cases: a life for a life, a man who commits adultery after being married.'"

"We were with 'Uthman when he was under siege and we could hear what was said from Al-Balat. 'Uthman came in one day, then he came out, and said: 'They are threatening to kill me.' We said: 'Allah will suffice you against them.' He said: 'Why would they kill me? I heard the Messenger of Allah [SAW] say: It is not permissible to shed the blood of a Muslim except in one of three cases: A man who reverts to Kufr after becoming Muslim, or commits adultery after being married, or one who kills a soul unlawfully. By Allah, I did not commit adultery during Jahiliyyah or in Islam, I never wished to follow any other religion since Allah guided me, and I have never killed anyone, so why do they want to kill me?'"

"I saw the Prophet [SAW] on the Minbar addressing the people. He said: 'After me there will be many calamities and much evil behavior. Whoever you see splitting away from the Jama'ah or trying to create division among the Ummah of Muhammad [SAW], then kill him, for the Hand of Allah is with the Jama'ah, and the Shaitan is with the one who splits away from the Ummah, running with him.'"

"The Prophet [SAW] said: 'After me there will be many calamities and much evil behavior.' He raised his hands (and said): 'Whomever you see trying to create division among the Ummah of Muhammad [SAW] when they are all united, kill him, no matter who he is among the people.'"

"I heard the Messenger of Allah [SAW] say: 'After me there will be many calamities and much evil behavior. Whoever wants to create division among the Ummah (of Muhammad [SAW]) when they are all united, strike him with the sword.'"

"The Messenger of Allah [SAW] said: 'Any man who goes out and tries to create division among my Ummah, strike his neck (kill him).'"

A group of eighty people from 'Ukl came to the Prophet [SAW], but the climate of Al-Madinah did not suit them and they fell sick. They complained about that to the Messenger of Allah [SAW] and he said: "Why don't you go out with our herdsmen and drink the milk and urine of the camels?" They said: "Yes (we will do that)." They went out and drank some of the (camels') milk and urine, and they recovered. Then they killed the herdsman of the Messenger of Allah [SAW], so he sent (men after them) and they caught them and brought them back. He had their hands and feet cut off and branded their eyes, and left them in the sun to die.
