Sifufenix: "Kill the apostate" is something quite easy to find back in the hadiths!
Hadith reference

The Hadith (the body of quotes attributed to Muhammad and claimed eyewitnesses' accounts of Muhammad's life and deeds) includes statements that Muslim scholars such as Sheikh Muhammed Salih Al-Munajjid see as supporting the death penalty for apostasy. [4] Only those from Sahih Bukhari, which are considered reliable by most Muslims generally are given below:

* "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." 9:83:17

* Narrated 'Ikrima: '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 [Muhammad] said, 'Don't punish (anybody) with Allah's Punishment.' No doubt, I would have killed them, for [Muhammad] said, 'If somebody (a Muslim) discards his religion, kill him.'" 4:52:260

* The legal regulation concerning the male and the female who reverts from Islam (apostates). Ibn 'Umar, Az-Zuhri and Ibrahim said, "A female apostate (who reverts from Islam), should be killed. And the obliging of the reverters from Islam (apostates) to repent. Allah said: — 'How shall Allah guide a people who disbelieved after their belief and (after) they bore witness that the Apostle (Muhammad) was true, and that Clear Signs had come unto them? And Allah does not guide the wrong-doing people. As for such the reward is that on them (rests) the curse of Allah, the Angels, and of all mankind. They will abide there-in (Hell). Neither will their torment be lightened nor it will be postponed (for a while). Except for those that repent after that and make amends. Verily Allah is Oft-Forgiving, Most Merciful. Surely those who disbelieved after their belief, and go on adding to their defiance of faith, never will their repentance be accepted, and they are those who have gone astray.' (Sura 3:86-90) Bukhari Volume 9, Book 84, Chapter 2, p. 42-43.

* 57. 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.'" 9:84:57

* 58. Narrated Abu Burda: Abu Musa said, "I came to [Muhammad] along with two men (from the tribe) of Ash'ariyin, one on my right and the other on my left, while Allah's Apostle was brushing his teeth (with a Siwak), and both men asked him for some employment. [Muhammad] said, 'O Abu Musa (O 'Abdullah bin Qais!).' I said, 'By Him Who sent you with the Truth, these two men did not tell me what was in their hearts and I did not feel (realize) that they were seeking employment.' As if I were looking now at his Siwak being drawn to a corner under his lips, and he said, 'We never (or, we do not) appoint for our affairs anyone who seeks to be employed. But O Abu Musa! (or 'Abdullah bin Qais!) Go to Yemen.'" [Muhammad] then sent Mu'adh bin Jabal after him and when Mu'adh reached him, he spread out a cushion for him and requested him to get down (and sit on the cushion). Behold: There was a fettered man beside Abu Musa. Mu'adh asked, "Who is this (man)?" Abu Muisa said, "He was a Jew and became a Muslim and then reverted back to Judaism." Then Abu Musa requested Mu'adh to sit down but Mu'adh said, "I will not sit down till he has been killed. This is the judgment of Allah and His Apostle (for such cases) 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 and one of us said, 'I pray and sleep, and I hope that Allah will reward me for my sleep as well as for my prayers.'" 9:84:58

* 271. Narrated Abu Musa: 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." 9:89:271
