‘And Abdullah bin Umar, Zuhri, and Ibrahim Nakha’i said: A female apostate should be killed. In this chapter, it is also mentioned that repentance should be sought from apostates. And Allah the Exalted has said (in Surah Al-Imran):“How shall Allah guide a people who disbelieved after their belief, and (after) they had borne witness that the Messenger (Muhammad, peace be upon him) is true, and clear proofs had come to them? And Allah does not guide the wrongdoing people. The recompense of such is that upon them is the curse of Allah and the angels and all mankind. They will abide therein (in the curse); their punishment will not be lightened, nor will they be reprieved. Except for those who repent after that and reform, for indeed, Allah is Forgiving, Merciful. Indeed, those who disbelieve after their belief and then increase in disbelief – never will their repentance be accepted, and those are the ones astray.”And He said:“O you who have believed, if you obey a party of those who were given the Scripture, they would turn you back, after your belief, to (being) disbelievers.”And in the twentieth ruku of Surah An-Nisa, He said:“Indeed, those who believed then disbelieved, then believed, then disbelieved, then increased in disbelief – Allah will not forgive them, nor will He guide them to a way.”And in the eighth ruku of Surah Al-Ma’idah, He said:“And whoever of you reverts from his religion (to disbelief) and dies while he is a disbeliever – never will their deeds be accepted in this world or the Hereafter, and those are the companions of the Fire; they will abide therein eternally.”And in the fourteenth ruku of Surah An-Nahl, He said:“But whoever disbelieves after his belief – except for one who is forced (to renounce his religion) while his heart is secure in faith – but those who (willingly) open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment. That is because they preferred the worldly life over the Hereafter and because Allah does not guide the disbelieving people. Those are the ones over whose hearts and hearing and vision Allah has set a seal, and it is those who are the heedless. Assuredly, in the Hereafter they will be the losers.”Until the end of the verse «إن ربك من بعدها لغفور رحيم» . And in the twenty-seventh ruku of Surah Al-Baqarah, He said:“They will not cease fighting you until they turn you back from your religion if they are able. And whoever of you reverts from his religion and dies while he is a disbeliever – for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire; they will abide therein eternally.”(Imam Bukhari, may Allah have mercy on him, has here gathered all the verses that have come in the Noble Qur’an regarding apostates.)

Narrated `Ikrima: 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.'"
