Ahimsa:
It’s hard to figure out the original meaning of a verse if you don’t know what the verse is talking about.
Muslims have been thinking for more than a thousand years, thank you very much.
Quotes from the
QURAN :
1 - Sura 9:73,74 -
“Prophet, make war on the unbelievers and the hypocrites and deal rigorously with them. Hell shall be their home: an evil fire. They swear by God that they said nothing. Yet they uttered the word of unbelief and renounced Islam after embracing it. They sought to do what they could not attain. Yet they had no reason to be spiteful except perhaps because God and His apostle had enriched them through His bounty. If they repent, it will indeed be better for them, but if they give no heed, God will sternly punish them, both in this world and in the world to come. They shall have none on this earth to protect or help them.”
2 - Sura 47:23-28 -
“If you renounced the faith, you would surely do evil in the land, and violate the ties of blood. Such are those on whom God has laid His curse, leaving them deaf and sightless… Those who return to unbelief after God’s guidance has been revealed to them are seduced by Satan and inspired by him…”
THE TEACHINGS OF THE HADITH (Sayings of Muhammad- hell-be-upon-him)
From the Hadith, we find no ambiguity on the subject.
All quotes will be from Bukhari’s Hadith, from the 9 volume English set, translated by Dr. Muhammad Muhsin Khan.
1 - Bukhari, volume 9, #17
"Narrated Abdullah: Allah’s Messenger said, “The blood of a Muslim who confesses that none has the right to be worshipped but Allah and that I am His Messenger, cannot be shed except in three cases: in Qisas (equality in punishment) for murder, a married person who commits illegal sexual intercourse and the one who reverts from Islam (Apostate) and leaves the Muslims.”
2 - Bukhari, volume 9, #37
"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…He replied “By Allah, Allah’s messenger 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 messenger, and deserted Islam and became an apostate…”
3 - Bukhari, volume 9, #57
Narrated Ikrima, "Some 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 messenger forbade it, saying, “Do not punish anybody with Allah’s punishment (fire).” I would have killed them according to the statement of Allah’s Messenger, “Whoever changed his Islamic religion, then kill him.”
4 - Bukhari, volume 9, #58
Narrated Abu Bruda, "Abu Musa said…Behold there was a fettered man beside Abu Musa. Muadh asked, “Who is this (man)?” Abu Musa said, “He was a Jew and became a Muslim and hen reverted back to Judaism.” Then Abu Musa requested Muadh to sit down but Muadh said, “I will not sit down till he has been killed. This is the judgment of Allah and his messenger,” and repeated it thrice. Then Abu Musa ordered that the man be killed, and he was killed. Abu Musa added, “Then we discussed the night prayers …”
5 - Bukhari, volume 9, #64
Narrated Ali, “Whenever I tell you a narration from Allah’s messenger, by Allah, I would rather fall down from the sky, than ascribe a false statement to him, but if I tell you something between me and you, (not a Hadith), then it was indeed a trick (i.e., I may say things just to cheat my enemy). No doubt I heard Allah’s messenger saying, ‘During the last days there will appear some young foolish people, who will say the best words, but their faith will not go beyond their throats (i.e. they will have no faith) and will go out from (leave) their religion as an arrow goes out of the game. So, wherever you find them, kill them, for whoever kills them shall have reward on the Day of Resurrection.’”
6 - Bukhari, volume 9, #271 [This one is similar to #58]
Narrated Abu Musa: A man embraced Islam and then reverted back to Judaism. Muadh Jabal came and saw the man with Abu Musa. Muadh asked, “What is wrong with this (man)?” Abu Musa replied, “He embraced Islam, and then reverted back to Judaism.” Muadh said, “I will not sit down unless you kill him (as it is) the verdict of Allah and His messenger.”
7 - Bukhari, Chapter 26, from the Book of Mutual Consultation, page 339, following Hadith # 461
"The Statement of Allah… 42:32, 3:5 -159, …The prophet said, “If someone changes his religion, then kill them…”
CONCLUSION
Muhammad taught that those who leave Islam are to be murdered, wherever they are.
This death sentence can be carried out wherever these Muslims are found, either in a Muslim country, or in a non-Muslim country.
The Quran supports this notion, and both the Hadith and Sirat establish this portion of Islamic law.
We do not know if he repented on his death bed
I mean, are they really that bad? I have had contacts with good ones. I am very very confused
