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!

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)

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."

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)

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,

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, "A faithful believer remains at liberty regarding his religion unless he kills somebody unlawfully."

`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.' "

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."

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, "There is no Diya for persons killed by animals or for the one who has been killed accidentally by falling into a well or for the one killed in a mine. And one-fifth of Rikaz (treasures buried before the Islamic era) is to be given to the state."

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."

We were with Uthman when he was besieged in the house. There was an entrance to the house. He who entered it heard the speech of those who were in the Bilat. Uthman then entered it. He came out to us, looking pale.

He said: They are threatening to kill me now. We said: Allah will be sufficient for you against them, Commander of the Faithful! He asked: Why kill me? I heard the Messenger of Allah (saws) say: It is not lawful to kill a man who is a Muslim except for one of the three reasons: Kufr (disbelief) after accepting Islam, fornication after marriage, or wrongfully killing someone, for which he may be killed.

I swear by Allah, I have not committed fornication before or after the coming of Islam, nor did I ever want another religion for me instead of my religion since Allah gave guidance to me, nor have I killed anyone. So for what reason do you want to kill me?

Abu Dawud said: 'Uthman and Abu Bakr (Allah be pleased with them) abandoned drinking wine in pre-Islamic times.

The day of Bu'ath was a day (i.e. battle) which Allah caused to take place just before the mission of His Apostle so that when Allah's Apostle came to Medina, they (the tribes) had divided (into hostile groups) and their nobles had been killed; and all that facilitated their conversion to Islam.

The Prophet said, "(Religious) knowledge will be taken away (by the death of religious scholars) ignorance (in religion) and afflictions will appear; and Harj will increase." It was asked, "What is Harj, O Allah's Apostle?" He replied by beckoning with his hand indicating "killing." (Fath-al-Bari Page 192, Vol. 1)

I heard the Prophet saying, "In the last days (of the world) there will appear young people with foolish thoughts and ideas. They will give good talks, but they will go out of Islam as an arrow goes out of its game, their faith will not exceed their throats. So, wherever you find them, kill them, for there will be a reward for their killers on the Day of Resurrection."

When `Ali was in Yemen, he sent some gold in its ore to the Prophet. The Prophet distributed it among Al-Aqra' bin H`Abis Al-Hanzali who belonged to Bani Mujashi, 'Uyaina bin Badr Al-Fazari, 'Alqama bin 'Ulatha Al-`Amiri, who belonged to the Bani Kilab tribe and Zaid AI-Khail at-Ta'i who belonged to Bani Nabhan. So the Quraish and the Ansar became angry and said, "He gives to the chiefs of Najd and leaves us!" The Prophet said, "I just wanted to attract and unite their hearts (make them firm in Islam)." Then there came a man with sunken eyes, bulging forehead, thick beard, fat raised cheeks, and clean-shaven head, and said, "O Muhammad! Be afraid of Allah! " The Prophet said, "Who would obey Allah if I disobeyed Him? (Allah). He trusts me over the people of the earth, but you do not trust me?" A man from the people (present then), who, I think, was Khalid bin Al- Walid, asked for permission to kill him, but the Prophet prevented him. When the man went away, the Prophet said, "Out of the offspring of this man, there will be people who will recite the Qur'an but it will not go beyond their throats, and they will go out of Islam as an arrow goes out through the game, and they will kill the Muslims and leave the idolators. Should I live till they appear, I would kill them as the Killing of the nation of 'Ad."

Al-Muhajirun (i.e. the Emigrants) and the Ansar were digging the trench around Medina and were carrying the earth on their backs while saying, "We are those who have given the pledge of allegiance to Muhammad for Islam as long as we live." The Prophet said in reply to their saying, "O Allah! There is no goodness except the goodness of the Hereafter; so please grant Your Blessing to the Ansar and the Emigrants." The people used to bring a handful of barley, and a meal used to be prepared thereof by cooking it with a cooking material (i.e. oil, fat and butter having a change in color and smell) and it used to be presented to the people (i.e. workers) who were hungry, and it used to stick to their throats and had a nasty smell.
