This topic is discussed on this forum many times and i want to copy and paste another member's explanation to the ahadees about Apostacy.
I think following shall clear the doubts in anyone's mind. :)
Not being in the Koran is one thing, rejected by the Koran is another thing. In this case, the Koran has rejected the punishment for Apostacy. And for something that Koran has outrightly rejected and disallowed, presenting Ahadith in its favor is a brave act. I'd fear Allah too much before committing such an act, but for those who do, I will hereby present on account on the punishment of Apostacy according to the Hadith, and the foul play by the Molvis in this regard:
-== A Rule from the Rules of Fiqh ==-
There is an accepted rule of Fiqh: ﺪﻴﻘﻤﻟﺍ ﻲﻠﻋ ﻖﻠﻄﻤﻟﺍ ﻞﻤﺤﻳ ﺎﻟ ﺎﻧ ﺪﻨﻋﻭ i.e. Mutlik is not Mahmool on Muqeed.
This is difficult language for a commoner, but it can be explained with the following example:
If a few people have seen X shot Y dead, then if, 10 of them say 'X has killed Y' and only 1 says 'X has killed Y because Y had first attacked him with a sword', then we will accept the statment of the 11th person, because it includes the statement of the other 10. The above rule means, that if 10 people have narrated the above incident without accepting or denying the fine details presented by the 11th, then we can not say that the 11th person is wrong, and Y had not attacked X with a sword first.
This rule is logically correct. We will need to keep this rule in mind in order to know the correct meaning of the Ahadith about Apostacy.
-== Hadith 1: ﺖﻋﺎﻤﺠﻠﻟ ﮎﺭﺎﺘﻟﺍ ﻪﻨﻳﺪﻟ ﻕﺭﺎﻔﻤﻟﺍ ==-
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."
In this Hadith, the Holy prophet has considered it legal to kill someone who leaves Islam and becomes an apostate. However, the Movlis hide from you all that this is NOT the only version of this Hadith. There are many versions of this Hadees, narrated by dependable narrators in the Sahee books. The other versions of the same Hadees, however, add some words to the condition of rhe punishment of Apostacy. These versions of the Hadith are intentionally hidden by the molvis, so that they can associate their barbarianism to Islam and make a mockery of Islam in the world.
Here are some other versions of the Hadith:
1- Narrated by Aisha in Sunan of Abu Daud: "The Apostle of Allah (peace_be_upon_him) Said: The blood of a Muslim man who testifies that there is no god but Allah and that Muhammad is Allah's Apostle should not lawfully be shed except only for one of three reasons: a man who committed fornication after marriage, in which case he should be stoned;** one who goes forth to fight with Allah and His Apostle, in which case he should be killed or crucified or exiled from the land**; or one who commits murder for which he is killed.
By changing the word "Apostate" with the words "one who goes forth to fight with Allah and His Apostle", which means this fighting against Allah and his prophet is a punishable act, and not apostacy in itself. Interestingly, other than death, this Hadith also gives an option of Exile. After reading this Hadith it becomes clear as to what type of apostates were killed, and for what reason.
2- Aisha narrates in Nissai the same hadith with the following words instead of an apostate: ﻪﻟﻮﺳﺭﻭ ﻪﻠﻟﺍ ﺏﺭﺎﺤﻴﻓ ﻡﺎﻠﺳﺎﻟﺍ ﻦﻣ ﺝﺮﺨﻳ ﻞﺟﺭ and also gives the option of exile as stated in the previous Hadith too.
3- Interestingly, in the very same Volume and very same Book of Bokhari, there is another version of the Hadith under discussion. It is sad that the Molvis show us one version and hide the other one.
In a long Hadith narrated Abu Qilaba: "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 Apostleand deserted Islam and became an apostate."
Note that this version of the Hadith makes it very very clear that in order to deserve a punishment, the apostate must have waged a war against Allah and his prophet! Islam allows a defensive war and thus such a killing is not against the Koran.
4- Narrated by Abu Qilaba again in Bokhari: "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**."
In this version, the words of Apostacy and changing of religion are completely gone, and replaced with the words "one who wages war against Allah and His Apostle".
Now, according to the rule mentioned at the start of this post, do you think we should take the hadith which says apostates should be killed, and throw away all the versions of the same hadith which describe as to what type of apostates are to be killed??? This is not a game, this issue involves human lives. Can a god fearing person play with the issue like our molvis do, by deliberately hiding some ahadith?
Why is it that the Molvis hide the descriptive versions of the Hadith, and only let people know of the one that could help them confuse the common people? It is a disgrace to Islam from these molvis to associate their filthy vulgar and barbaric way of thinking to Islam, by hiding the ahadith which go against their opinion, and popularizing the ones that are against the rules of conscience and against the teachings of Koran!
