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.'"

Yahya related to me from Malik from Zayd ibn Aslam that the Messenger of Allah, may Allah bless him and grant him peace, said, "If someone changes his deen - strike his neck!"

The meaning of the statement of the Prophet, may Allah bless him and grant him peace, in our opinion and Allah knows best, is that "if someone changes his deen, strike his neck!" refers to those who leave Islam for other than it - like the heretics and their like, about whom it is known. They are killed without being called to tawba because their tawba is not recognised. They were hiding their kufr and publishing their Islam, so I do not think that one calls such people to tawba, and one does not accept their word. As for the one who goes out of Islam to something else and divulges it, one calls him to tawba. If he does not turn in tawba, he is killed. If there are people in that situation, I think that one should call them to Islam and call them to tawba. If they turn in tawba, that is accepted from them. If they do not turn in tawba, they are killed. That does not refer as we see it, and Allah knows best, to those who come out of Judaism to Christianity or from Christianity to Judaism, nor to someone who changes his deen from the various forms of deen except for Islam. Whoever comes out of Islam to other than it and divulges that, that is the one who is referred to, and Allah knows best!

The Prophet said, "Whoever swears by a religion other than Islam (i.e. if he swears by saying that he is a non-Muslim in case he is telling a lie), then he is as he says if his oath is false and whoever commits suicide with something, will be punished with the same thing in the (Hell) fire, and cursing a believer is like murdering him, and whoever accuses a believer of disbelief, then it is as if he had killed him."

The Prophet said, "Whoever swears by a religion other than Islam, is, as he says; and whoever commits suicide with something, will be punished with the same thing in the (Hell) Fire; and cursing a believer is like murdering him; and whoever accuses a believer of disbelief, then it is as if he had killed him."

(who was one of the companions who gave the pledge of allegiance to the Prophet underneath the tree (Al-Hudaibiya)) Allah's Apostle said, "Whoever swears by a religion other than Islam (i.e. if somebody swears by saying that he is a non-Muslim e.g., a Jew or a Christian, etc.) in case he is telling a lie, he is really so if his oath is false, and a person is not bound to fulfill a vow about a thing which he does not possess. And if somebody commits suicide with anything in this world, he will be tortured with that very thing on the Day of Resurrection; And if somebody curses a believer, then his sin will be as if he murdered him; And whoever accuses a believer of Kufr (disbelief), then it is as if he killed him."

An ally of Bani Zuhra who took part in the battle of Badr with the Prophet, that he said, "O Allah's Apostle! If I meet an unbeliever and we have a fight, and he strikes my hand with the sword and cuts it off, and then takes refuge from me under a tree, and says, 'I have surrendered to Allah (i.e. embraced Islam),' may I kill him after he has said so?" Allah's Apostle said, "Do not kill him." Al- Miqdad said, "But O Allah's Apostle! He had chopped off one of my hands and he said that after he had cut it off. May I kill him?" The Prophet said. "Do not kill him for if you kill him, he would be in the position in which you had been before you kill him, and you would be in the position in which he was before he said the sentence." The Prophet also said to Al-Miqdad, "If a faithful believer conceals his faith (Islam) from the disbelievers, and then when he declares his Islam, you kill him, (you will be sinful). Remember that you were also concealing your faith (Islam) at Mecca before."

That a man came to him (while two groups of Muslims were fighting) and said, "O Abu `Abdur Rahman! Don't you hear what Allah has mentioned in His Book: 'And if two groups of believers fight against each other...' (49.9) So what prevents you from fighting as Allah has mentioned in His Book?"' Ibn `Umar said, "O son of my brother! I would rather be blamed for not fighting because of this Verse than to be blamed because of another Verse where Allah says: 'And whoever kills a believer intentionally..." (4.93) Then that man said, "Allah says:-- 'And fight them until there is no more afflictions (worshipping other besides Allah) and the religion (i.e. worship) will be all for Allah (Alone)" (8.39) Ibn `Umar said, "We did this during the lifetime of Allah's Apostle when the number of Muslims was small, and a man was put to trial because of his religion, the pagans would either kill or chain him; but when the Muslims increased (and Islam spread), there was no persecution." When that man saw that Ibn `Umar did not agree to his proposal, he said, "What is your opinion regarding `Ali and `Uthman?" Ibn `Umar said, "What is my opinion regarding `Ali and `Uthman? As for `Uthman, Allah forgave him and you disliked to forgive him, and `Ali is the cousin and son-in-law of Allah's Apostle ." Then he pointed out with his hand and said, "And that is his daughter's (house) which you can see."

Allah's Apostle said, "Every child is born with a true faith of Islam (i.e. to worship none but Allah Alone) but his parents convert him to Judaism, Christianity or Magainism, as an animal delivers a perfect baby animal. Do you find it mutilated?" Then Abu Huraira recited the holy verses: "The pure Allah's Islamic nature (true faith of Islam) (i.e. worshipping none but Allah) with which He has created human beings. No change let there be in the religion of Allah (i.e. joining none in worship with Allah). That is the straight religion (Islam) but most of men know, not." (30.30)

The Prophet sent Khalid bin Al-Walid to the tribe of Jadhima and Khalid invited them to Islam but they could not express themselves by saying, "Aslamna (i.e. we have embraced Islam)," but they started saying "Saba'na! Saba'na (i.e. we have come out of one religion to another)." Khalid kept on killing (some of) them and taking (some of) them as captives and gave every one of us his Captive. When there came the day then Khalid ordered that each man (i.e. Muslim soldier) should kill his captive, I said, "By Allah, I will not kill my captive, and none of my companions will kill his captive." When we reached the Prophet, we mentioned to him the whole story. On that, the Prophet raised both his hands and said twice, "O Allah! I am free from what Khalid has done."

Allah's Apostle said, "No child is born except on Al-Fitra (Islam) and then his parents make him Jewish, Christian or Magian, as an animal produces a perfect young animal: do you see any part of its body amputated?" Then he recited 'The religion of pure Islamic Faith (Hanifa),(i.e. to worship none but Allah), The pure Allah's Islamic nature with which He (Allah) has created mankind. Let There be no change in Allah's religion (i.e. to join none in Allah's worship). That is the straight religion; but most of men know not..." (30.30)

`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.' "

When it was the day of (the battle of) Hunain, I saw a Muslim man fighting with one of the pagans and another pagan was hiding himself behind the Muslim in order to kill him. So I hurried towards the pagan who was hiding behind the Muslim to kill him, and he raised his hand to hit me but I hit his hand and cut it off. That man got hold of me and pressed me so hard that I was afraid (that I would die), then he knelt down and his grip became loose and I pushed him and killed him. The Muslims (excepting the Prophet and some of his companions) started fleeing and I too, fled with them. Suddenly I met `Umar bin Al-Khattab amongst the people and I asked him, "What is wrong with the people?" He said, "It is the order of Allah" Then the people returned to Allah's Apostle (after defeating the enemy). Allah's Apostle said, "Whoever produces a proof that he has killed an infidel, will have the spoils of the killed man." So I got up to look for an evidence to prove that I had killed an infidel, but I could not find anyone to bear witness for me, so I sat down. Then it came to my mind (that I should speak of it) and I mentioned the case to Allah's Apostle. A man from the persons who were sitting with him (i.e. the Prophet), said, "The arms of the deceased one whom he ( i.e. Abu Qatada) has mentioned, are with me, so please compensate him for it (i.e. the spoils)," Abu Bakr said, "No, Allah's Apostle will not give it (i.e. the spoils) to a weak humble person from Quraish and leave one of Allah's Lions who fights on behalf of Allah and His Apostle." Allah's Apostle then got up and gave that (spoils) to me, and I bought with it, a garden which was the first property I got after embracing Islam.

A man said, "O Allah's Apostle! Shall we be punished for what we did in the Prelslamic Period of ignorance?" The Prophet said, "Whoever does good in Islam will not be punished for what he did in the Pre-lslamic Period of ignorance and whoever does evil in Islam will be punished for his former and later (bad deeds).

`AbdurRahman bin Abza said, "Ask Ibn `Abbas about these two Qur'anic Verses: 'Nor kill such life as Allah has made sacred, Except for just cause.' (25.168) "And whoever kills a believer intentionally, his recompense is Hell. (4.93) So I asked Ibn `Abbas who said, "When the Verse that is in Sura-al-Furqan was revealed, the pagans of Mecca said, 'But we have slain such life as Allah has made sacred, and we have invoked other gods along with Allah, and we have also committed fornication.' So Allah revealed:-- 'Except those who repent, believe, and do good-- (25.70) So this Verse was concerned with those people. As for the Verse in Surat-an-Nisa (4-93), it means that if a man, after understanding Islam and its laws and obligations, murders somebody, then his punishment is to dwell in the (Hell) Fire forever." Then I mentioned this to Mujahid who said, "Except the one who regrets (one's crime) . "

A man embraced Islam and then reverted back to Judaism. Mu`adh bin Jabal came and saw the man with Abu Musa. Mu`adh asked, "What is wrong with this (man)?" Abu Musa replied, "He embraced Islam and then reverted back to Judaism." Mu`adh said, "I will not sit down unless you kill him (as it is) the verdict of Allah and His Apostle.

Allah's Apostle said, "A faithful believer remains at liberty regarding his religion unless he kills somebody unlawfully."

Abu Umamah bin Sahl bin Hunaif narrated: I was with `Uthman (رضي الله عنه) in the house when he was under siege. We would enter through an entrance... and he narrated a similar hadeeth. And he said: I heard the Messenger of Allah (ﷺ) say:... and he narrated a similar hadeeth,
