Sayyiduna Abu Burdah (may Allah be pleased with him) narrates that Sayyiduna Abu Musa Ash’ari (may Allah be pleased with him) was in Yemen and Sayyiduna Mu’adh bin Jabal (may Allah be pleased with him) came to him. There was a man with him. Sayyiduna Mu’adh (may Allah be pleased with him) asked: Who is this? The people said: This man was a Jew, then he became a Muslim, and now he has become a Jew again. It has been two months that we have been demanding from him to adhere to Islam. Sayyiduna Mu’adh (may Allah be pleased with him) said: By Allah! I will not sit until you strike his neck. So he was killed. Then he said that the Messenger of Allah (peace and blessings be upon him) had given this ruling: Whoever leaves his religion or changes his religion, kill him.

It is narrated from ‘Ikrimah that some heretics were brought to Sayyiduna ‘Ali (may Allah be pleased with him), and they had their books with them. Sayyiduna ‘Ali (may Allah be pleased with him) first ordered a fire to be kindled, so a fire was lit, then he burned them and their books. When Sayyiduna Ibn ‘Abbas (may Allah be pleased with them both) learned of this incident, he said: If I had been there, I would not have burned them, because the Noble Prophet (peace and blessings be upon him) forbade burning. However, I would have killed them, because the Prophet (peace and blessings be upon him) said: Whoever changes his religion, kill him. Also, the Prophet (peace and blessings be upon him) said: Do not punish people with the punishment of Allah the Exalted.

. (Second chain) Sayyiduna Ali (may Allah be pleased with him) burned some people who had apostatized from Islam with fire. When Sayyiduna Ibn Abbas (may Allah be pleased with them both) learned of this incident, he said: If I had been there, I would not have burned them with fire, because the Noble Prophet (peace and blessings of Allah be upon him) said: Do not punish people with Allah’s punishment. I would have killed them, because the Noble Prophet (peace and blessings of Allah be upon him) said: Whoever changes his religion, kill him. When Sayyiduna Ali (may Allah be pleased with him) learned of this, he said: Woe to Ibn Abbas.

Under this chapter, the following sub-chapters and hadiths have been mentioned.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When an adulterer commits adultery, he is not a believer at that moment; when a thief steals, he is not a believer at that moment; and when a drunkard drinks alcohol, he is not a believer at that moment. And (even after these crimes) the door of repentance remains open.

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: On the Day of Resurrection, Allah Almighty will not look at three types of people: a lying imam, an old adulterer, and an arrogant poor person.

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, was asked about the thing due to which most people will enter Hell. He, peace and blessings be upon him, said: Two things related to the belly, that is, the mouth and the private parts. Then he, peace and blessings be upon him, was asked about the thing due to which most people will enter Paradise. He, peace and blessings be upon him, said: It is good character.

It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever safeguards that which is between his jaws and his private parts, he will enter Paradise.

It is narrated from Sayyiduna Abu Umamah Ansari (may Allah be pleased with him) that an Ansari youth came to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Grant me permission to commit adultery. The people turned upon him and said: Be quiet, be quiet! But the Prophet (peace and blessings be upon him) said to the youth: Come closer. So he came near and sat close to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: Would you like this for your mother? He replied: By Allah, never! May Allah make me a sacrifice for you. The Prophet (peace and blessings be upon him) said: Likewise, people do not like this evil for their mothers. Then the Prophet (peace and blessings be upon him) said: Would you like this for your daughter? He replied: No, by Allah! May Allah make me a sacrifice for you. The Prophet (peace and blessings be upon him) said: People also do not like this evil for their daughters. The Prophet (peace and blessings be upon him) said: Would you like adultery for your sister? He replied: May Allah make me a sacrifice for you, I would never like this for my sister. The Prophet (peace and blessings be upon him) said: People also do not like this evil for their sisters. The Prophet (peace and blessings be upon him) said: Would you like this for your paternal aunt? He replied: No, by Allah, I would not like it, may Allah make me a sacrifice for you. The Prophet (peace and blessings be upon him) said: Then people also do not like this for their paternal aunts. The Prophet (peace and blessings be upon him) said: Tell me, would you like this evil for your maternal aunt? He replied: No, by Allah! I would not like it, may Allah make me a sacrifice for you. The Prophet (peace and blessings be upon him) said: Then people also do not like this evil for their maternal aunts. The Prophet (peace and blessings be upon him) placed his blessed hand upon him and prayed for him: O my Allah! Forgive his sins, purify his heart, and guard his chastity. After that, the youth never turned towards anything (evil) again.

Narrated by Umm al-Mu’minin Sayyida Maymunah (may Allah be pleased with her): The Noble Prophet (peace and blessings be upon him and his family) said: My Ummah will remain upon goodness as long as illegitimate children do not become numerous among them. When illegitimate children become numerous among them, it will be near that Allah Almighty will inflict a general punishment upon them.
