Ibn 'Abbas narrated that : There was a blind man during the time of the Messenger of Allah (ﷺ) who had an Umm Walad by whom he had two sons. She used to slander and defame the Messenger of Allah (ﷺ) a great deal, and he would rebuke her, but she would not pay heed, and he would forbid her to do that, but she ignored him. (The blind man said) One night I mentioned the Prophet (ﷺ) , and she slandered him. I could not bear it so I went and got a dagger which I thrust into her stomach and leaned upon it, and killed her. In the morning she was found slain. Mention of that was made to the Prophet (ﷺ) and he gathered the people and said: "I adjure by Allah; a man over whom I have the right, that he should obey me, and he did what he did, to stand up." The blind man started to tremble and said: "O Messenger of Allah , I am the one who killed her. She was my Umm Walad and she was kind and gentle toward me, and I have two sons like pearls from her, but she used to slander and defame you a great deal. I forbade her, but she did not stop, and I rebuked her, but she did not pay heed. Finally, I mentioned your name and she slandered you, so I went and got a dagger which I thrust into her stomach, and leaned on it until I killed her. The Messenger of Allah (ﷺ) said: "I bear witness that her blood is permissible."

It was narrated that Abu Barzah said: "Abu Bakr got infuriated with a man, and I said: 'Who is he, O Khalifah of the Messenger of Allah?' He said: 'Why?' I said: 'So that I might strike his neck (killing him) if you tell me to.' He said: 'Would you really do that?' I said: 'Yes. By Allah,' the seriousness of what I said took away his anger. Then he said: 'That is not for anyone after Muhammad .'"

It was narrated that Abu Barzah said: "I passed by Abu Bakr and he was furious with one of his companions. I said: 'O Khalifah of the Messenger of Allah, who is the one with whom you are furious?' He said: 'Why are you asking about him?' I said: 'I will strike his neck (kill him).' By Allah, the seriousness of what I said took away his anger. Then he said: 'That is not for anyone after Muhammad .'"

It was narrated from Abu Nadrah, that Abu Barzah said: "Abu Bakr got very angry with a man, so much so that his color changed. I said: 'O Khalifah of the Messenger of Allah, if you tell me to, I will strike his neck (kill him).' It was as if cold water had been poured on him and he became calm. He said: 'May your mother be bereft of you, Abu Barzah! That is not for anyone after the Messenger of Allah (ﷺ) .'"

Abu Nasr narrated from Abu Barzah, that he said: "I came to Abu Bakr when he had spoken harshly to a man who had answered back. I said: 'Shall I not strike his neck (kill him)?' He rebuked me, and said: 'That is not for anyone after the Messenger of Allah (ﷺ) .'"

It was narrated that Safwan bin 'Assal said: "A Jew said to his companion: 'Let us go to this Prophet.' His companion said to him: 'Do not say Prophet; if he hears you, he will become big-headed.' So they came to the Messenger of Allah (ﷺ) and asked him about nine clear signs. He said to them: 'Do not associate anything with Allah, do not steal, do not commit adultery, do not kill any soul whom Allah has forbidden you to kill, except by right, do not speak falsely about an innocent man before a ruler, do not engage in magic, do not consume Riba (usury), do not slander chaste women, and do not flee on the day of the march (to battle). And for you Jews especially, do not break the Sabbath.' They kissed his hands and feet and said: 'We bear witness that you are a Prophet.' He said: 'What is keeping you from following me?' They said: 'Dawud prayed that there would always be a Prophet among his descendants, and we are afraid that if we follow you, the Jews will kill us.'"

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'Whoever ties a know and blows on it, he has practiced magic; and whoever practices magic, he has committed Shirk; and whoever hangs up something (as an amulet) will be entrusted to it.'"

It was narrated from Qabus bin Mukhariq that his father said: "I heard Sufyan Ath-Thawri narrating this Hadith. He said: 'A man came to the Prophet (ﷺ) and said: "What if a man comes to me and wants to take my wealth?" He said: "Remind him of Allah." He said: "What if he pays no heed?" He said: "Seek the help of the Muslims around you against him." He said: "What if there are no Muslims around me?" He said: "Seek the help of the ruler against him." He said: "What if the ruler is far away from me?" He said: "Fight to defend your wealth until you either become one of the martyrs of the Hereafter, or you protect your wealth (successfully)."

It was narrated from Ibrahim bin Muhammad bin Talhah that he heard 'Abdullah bin 'Amr narrating: From the Prophet (ﷺ) , that he said: "If a person's wealth is sought without right, and he fights (to protect it) and is killed, he is a martyr."

It was narrated that Abu Sa'eed Al-Khudri said: "When 'Ali was in Yemen, he sent some gold that was still enclosed in rock to the Prophet (ﷺ) , who distributed it among Al-Aqra' bin Habis Al-Hanzali, who belonged to Banu Mujashi', 'Uyaynah bin Badr Al-Fazari, 'Alqamah bin 'Ulathah Al-'Amiri, who belonged to Banu Kilab and Zaid Al-Khail At-Ta'I, who belonged to Banu Nabhan. The Quraish and the Ansar became angry and said: 'He gives to the chiefs of Najd and ignores us!' He said: 'I am seeking to win them over (firmly to Islam).' Then a man with sunken eyes, a bulging forehead, a thick beard and a shaven head came and said: 'O Muhammad, fear Allah!' He said: 'Who will obey Allah if I do not? He trusts me with the people of this Earth but you do not trust me.' A man among the people asked for permission to kill him, but he did not let him do that. When (the man) went away, he (the Prophet (ﷺ) ) said: 'Among 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 through the target. They will kill the Muslims and leave the idol-worshippers alone. If I live to see them, I will kill them as the killing of 'Ad.'"

it was narrated that Sharik bin Shihab said: "I used to wish that I could meet a man among the Companions of the Prophet (ﷺ) and ask him about the Khawarij. Then I met Abu Barzah on the day of 'Id, with a number of his companions. I said to him: 'Did you hear the Messenger of Allah (ﷺ) mention the Khawarij?' He said: 'Yes. I heard the Messenger of Allah (ﷺ) with my own ears, and saw him with my own eyes. Some wealth was brought to the Messenger of Allah (ﷺ) and he distributed it to those on his right and on his left, but he did not give anything to those who were behind him. Then a man stood behind him and said: "O Muhammad! You have not been just in your division!" He was a man with black patchy (shaved) hair, wearing two white garments. So Allah's Messenger (ﷺ) became very angry and said: "By Allah! You will not find a man after me who is more just than me." Then he said: "A people will come at the end of time; as if he is one of them, reciting the Qur'an without it passing beyond their throats. They will go through Islam just as the arrow goes through the target. Their distinction will be shaving. They will not cease to appear until the last of them comes with Al-Masih Ad-Dajjal. So when you meet them, then kill them, they are the worst of created beings."
