The Messenger of Allah [SAW] said: "I have been commanded to fight the idolators until they bear witness to La ilaha illallah (there is none worthy of worship except Allah) and that Muhammad is the Messenger of Allah [SAW]. If they bear witness to La ilaha illallah and that Muhammad is the Messenger of Allah [SAW], and they face our Qiblah, eat our slaughtered animals, and pray as we do, then their blood and wealth become forbidden except for a right that is due, and they will have the same rights and obligations as the Muslims."

"When the Messenger of Allah [SAW] died, and Abu Bakr (became Khalifah) after him, and the 'Arabs reverted to Kufr, 'Umar said: 'O Abu Bakr, how can you fight the people when the Messenger of Allah [SAW] said: I have been commanded to fight the people until they say La ilaha illallah, and whoever says La ilaha illallah, his wealth and his life are safe from me, except for a right that is due, and his reckoning will be with Allah, the Mighty and Sublime?' Abu Bakr said: 'I will fight whoever separates Salah and Zakah, for Zakah is the compulsory right to be taken from wealth. By Allah, if they withhold from me a young goat that they used to give to the Messenger of Allah [SAW], I will fight them for withholding it.' 'Umar said: 'By Allah, as soon as I saw that Allah has expanded the chest of Abu Bakr to fighting, I knew that it was the truth.'"

The Messenger of Allah [SAW] said: "I have been commanded to fight the people until they say La ilaha illallah, and whoever says it, his life and his wealth are safe from me, except for a right that is due, and his reckoning will be with Allah."

"We were with the Messenger of Allah [SAW] and a man came and whispered to him. He said: 'Kill him.' Then he said: 'Does he bear witness to La ilaha illallah (there is none worthy of worship except Allah)?' He said: 'Yes, but he is only saying it to protect himself.' The Messenger of Allah [SAW] said: 'Do not kill him, for I have been commanded to fight the people until they say La ilaha illallah, and if they say it, their blood and their wealth are safe from me, except for a right that is due, and their reckoning will be with Allah.'"

"I heard Aws say: 'The Messenger of Allah [SAW] came to us when we were in a tent.'" And he quoted the same Hadith.

'Amr bin Aws told him that his father Aws said: "The Messenger of Allah [SAW] said: 'I have been commanded to fight the people until they bear witness to La ilaha illallah (there is none worthy of worship except Allah), then their blood and their wealth become forbidden to me, except for a right that is due."

"The Messenger of Allah [SAW] said: 'By the One in Whose Hand is my soul, killing a believer is more grievous before Allah than the extinction of the whole world.'"

"The Messenger of Allah [SAW] said: 'Killing a believer is more grievous before Allah than the extinction of the whole world.'"

"The first matter concerning which scores will be settled among the people will be bloodshed."

Ibn 'Abbas was asked about someone who killed a believer deliberately, then he repented, believed and did righteous deeds, and followed true guidance. Ibn 'Abbas said: "There is no way the repentance could avail him! I heard the Prophet [SAW] say: 'He (the victim) will come hanging onto his killer, with his jugular veins flowing with blood and saying: O Lord, ask him why he killed me. Then he said: By Allah, Allah revealed it and never abrogated anything of it.'"

"I said to Ibn 'Abbas: 'Can a person, who killed a believer intentionally, repent?' He said: 'No.' I recited the Verse from Al-Furqan to him: 'And those who invoke not any other ilah (god) along with Allah, or kill such person as Allah has forbidden, except by right,' he said: 'This Verse was revealed in Makkah and was abrogated by a Verse that was revealed in Al-Madinah: 'And whoever kills a believer intentionally, his recompense is Hell.'"

Some of the people of Shirk came to Muhammad [SAW] and said: "What you say and call people to is good, if only you could tell us that there is any expiation for what we have done." Then the Verses: "And those who invoke not any other ilah (god) along with Allah, or kill such a person as Allah has forbidden, except by right." And "Say: O 'Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)" were revealed.

"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."

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."

"When the Messenger of Allah [SAW] died, the 'Arabs apostatized, so 'Umar said: 'O Abu Bakr, how can you fight the 'Arabs?' Abu Bakr said: 'The Messenger of Allah [SAW] said: "I have been commanded to fight the people until they bear witness to La ilaha illallah (there is none worthy of worship except Allah) and that I am the Messenger of Allah, and they establish Salah and pay Zakah." By Allah, if they withhold from me a young goat that they used to give to the Messenger of Allah [SAW], I will fight them for it.' 'Umar said: 'By Allah, as soon as I realized how certain Abu Bakr was, I knew that it was the truth.'"

The Messenger of Allah [SAW] said: "I have been commanded to fight the people until they say La ilaha illallah (there is none worthy of worship but Allah). Whoever says La ilaha illallah, his wealth and his life are safe from me except for a right that is due, and his reckoning will be with Allah."

"So Abu Bakr decided to fight them, then 'Umar said: 'O Abu Bakr, how can you fight the people when the Messenger of Allah [SAW] said: "I have been commanded to fight the people until they say La ilaha illallah, and if they say it, their blood and their wealth will be safe from me except for a right that is due.?' Abu Bakr said: 'I will fight whoever separates prayer and Zakah. By Allah, if they withhold from me a young goat that they used to give to the Messenger of Allah [SAW], I will fight them for withholding it.' 'Umar said: 'By Allah, as soon as I realized that Allah has expanded the chest of Abu Bakr to fight them, I knew that it was the truth.'"

"The Messenger of Allah [SAW] said: 'I have been commanded to fight the people until they say La ilaha illallah. If they say it, then their blood and wealth are prohibited for me, except for a right that is due, and their reckoning will be with Allah, the Mighty and Sublime."

"The Messenger of Allah [SAW] said: 'I have been commanded to fight the people until they say La ilaha illallah. If they say it, then their blood and wealth are prohibited for me, except for a right that is due, and their reckoning will be with Allah.'"

The Messenger of Allah [SAW] said: "We will fight the people until they say La ilaha illallah. If they say La ilaha illallah then their blood and their wealth become forbidden to us, except for a right that is due, and their reckoning will be with Allah."
