'Uthman said: "I heard the Messenger of Allah [SAW] say: 'It is not permissible to shed the blood of a Muslim except in three cases: A man who commits adultery after having married; or one who kills intentionally, in which case he deserves retaliation; or one who apostatizes after having become Muslim, in which case he deserves to be killed.'" (Using translation from Nasāʾī 4057)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَا يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلَّا بِإِحْدَى ثَلَاثٍ رَجُلٌ زَنَى بَعْدَ إِحْصَانِهِ فَعَلَيْهِ الرَّجْمُ أَوْ قَتَلَ عَمْدًا فَعَلَيْهِ الْقَوَدُ أَوِ ارْتَدَّ بَعْدَ إِسْلَامِهِ فَعَلَيْهِ الْقَتْلُ  

"I heard the Messenger of Allah [SAW] say: 'It is not permissible to shed the blood of a Muslim except in three cases: A man who commits adultery after having married; or one who kills another person, who is to be killed; or who reverts to Kufr after having accepted Islam, who is to be killed.'" (Using translation from Nasāʾī 4058)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَا يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلَّا بِثَلَاثٍ أَنْ يَزْنِيَ بَعْدَمَا أُحْصِنَ أَوْ يَقْتُلَ إِنْسَانًا فَيُقْتَلَ أَوْ يَكْفُرَ بَعْدَ إِسْلَامِهِ فَيُقْتَلَ  

“Whoever changes his religion, execute him.” (Using translation from Ibn Mājah 2535)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُ»  

"Some people apostatized after accepting Islam, and 'Ali burned them with fire. Ibn 'Abbas said: 'If it had been me, I would not have burned them; the Messenger of Allah [SAW] said: 'No one should be punished with the punishment of Allah.' If it had been me, I would have killed them; the Messenger of Allah [SAW] said: 'Whoever changes his religion, kill him.'" (Using translation from Nasāʾī 4060)  

قَالَ رَسُولُ اللهِ ﷺ «لَا تُعَذِّبُوا بِعَذَابِ اللهِ أَحَدًا» وَلَوْ كُنْتُ أَنَا لَقَتَلْتُهُمْ قَالَ رَسُولُ اللهِ ﷺ «مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُ»

"That the Prophet [SAW] sent him to Yemen, then he sent Mu'adh bin Jabal after that. When he arrived he said: 'O people, I am the envoy of the Messenger of Allah [SAW] to you.' Abu Musa gave him a cushion to sit down, then a man was brought who had been a Jew, then he became a Muslim, then he reverted to Kufr. Mu'adh said: 'I will not sit down until he is killed; this is the decree of Allah and His Messenger,' (saying it) three times. When he was killed, he sat down." (Using translation from Nasāʾī 4066)  

أَنَّ النَّبِيَّ ﷺ بَعَثَهُ إِلَى الْيَمَنِ ثُمَّ أَرْسَلَ مُعَاذَ بْنَ جَبَلٍ بَعْدَ ذَلِكَ فَلَمَّا قَدِمَ قَالَ أَيُّهَا النَّاسُ إِنِّي رَسُولُ رَسُولِ اللهِ ﷺ إِلَيْكُمْ فَأَلْقَى لَهُ أَبُو مُوسَى وِسَادَةً لِيَجْلِسَ عَلَيْهَا فَأُتِيَ بِرَجُلٍ كَانَ يَهُودِيًّا فَأَسْلَمَ ثُمَّ كَفَرَ قَالَ مُعَاذٌ «لَا أَجْلِسُ حَتَّى يُقْتَلَ قَضَاءُ اللهِ وَرَسُولِهِ ثَلَاثَ مِرَارٍ فَلَمَّا قُتِلَ قَعَدَ»  

"On the day of the Conquest of Makkah, the Messenger of Allah [SAW] granted amnesty to the people, except four men and two women. He said: 'Kill them, even if you find them clinging to the covers of Ka'bah.' (They were) 'Ikrimah bin Abi Jahl, 'Abdullah bin Khatal, Miqyas bin Subabah and 'Abdullah bin Sa'd bin Abi As-Sarh. 'Abdullah bin Khatl was caught while he was clinging to the covers of Ka'bah. Sa'eed bin Huraith and 'Ammar bin Yasir both rushed toward him, but Sa'eed, who was the younger of the two, got there before 'Ammar, and he killed him. Miqyas bin Subabah was caught by the people in the marketplace, and they killed him. 'Ikrimah traveled by sea, and he was caught in a storm. The crew of the ship said: 'Turn sincerely toward Allah, for your (false) gods cannot help you at all in this situation.' 'Ikrimah said: 'By Allah, if nothing came to save me at sea except sincerity toward Allah then nothing else will save me on land. O Allah, I promise You that if You save me from this predicament I will go to Muhammad [SAW] and put my hand in his, and I am sure that I will find him generous and forgiving.' So he came, and accepted Islam. 'Abdullah (bin Sa'd) bin Abi Sarh hid in the house of 'Uthman bin 'Affan, and when the Messenger of Allah [SAW] called the people to give their Oath of Allegiance, he brought him, and made him stand before the Prophet [SAW]. He ('Uthman) said: 'O Messenger of Allah! Accept the allegiance of 'Abdullah.' He raised his head and looked at him three times, refusing his allegiance each time, then he accepted his allegiance after three times. Then he turned to his Companions and said: 'Was there not any sensible man among you who would get up when he saw me refusing to give him my hand and kill him?' They said: 'We did not know, O Messenger of Allah, what was in your heart. Why did you not gesture to us with your eyes?' He said: 'It is not befitting for a Prophet that his eyes be deceitful.'" (Using translation from Nasāʾī 4067)
