Sahih al-Bukhari 371—When Allah’s Messenger invaded Khaibar, we offered the Fajr prayer there (early in the morning) when it was still dark. Allah’s Prophet rode and Abu Talha rode, too, and I was riding behind Abu Talha. Allah’s Prophet passed through the lane of Khaibar quickly and my knee was touching the thigh of Allah’s Prophet. Then his thigh was uncovered by the shift of his Izar (waist-sheet), and I saw the whiteness of the thigh of Allah’s Prophet. When he entered the town, he said, “Allahu Akbar! Khaibar is ruined. Whenever we approach near a (hostile) nation (to fight) then evil will be the morning of those who have been warned.” He repeated this thrice. The people came out for their jobs and some of them said, “Muhammad (has come) along with his army.” We conquered Khaibar, (took the captives), and the booty was collected. Dihya came and said, “O Allah’s Prophet! Give me a slave-girl from the captives.” The Prophet said, “Go and take any slave-girl.” He took Safiyya bint Huyai.
Ibn Ishaq, Sirat Rasul Allah, 511—We came to Khaybar by night, and the apostle passed the night there; and when morning came he did not hear the call to prayer, so he rode and we rode with him, and I rode behind Abu Talha with my foot touching the apostle’s foot. We met the workers of Khaybar coming out in the morning with their spades and baskets. When they saw the apostle and the army they cried, “Muhammad with his force,” and turned tail and fled. The apostle said, “Allah akbar! Khaybar is destroyed. When we arrive in a people’s square it is a bad morning for those who have been warned.” . . . The apostle seized the property piece by piece and conquered the forts one by one as he came to them. . . . The women of Khaybar were distributed among the Muslims.
Sahih Muslim 3328—Anas reported: I was sitting behind Abu Talha on the Day of Khaibar and my feet touched the foot of Allah’s Messenger, and we came (to the people of Khaibar) when the sun had risen and they had driven out their cattle, and had themselves come out with their axes, large baskets and hatchets, and they said: (Here come) Muhammad and the army. Allah’s Messenger said: Khaibar is ruined. Verily when we get down in the valley of a people, evil is the morning of the warned ones (al-Qur’an, xxxvii. 177). Allah, the Majestic and the Glorious, defeated them (the inhabitants of Khaibar), and there fell to the lot of Dihya a beautiful girl, and Allah’s Messenger got her in exchange of seven heads, and then entrusted her to Umm Sulaim so that she might embellish her and prepare her (for marriage) with him.
Sahih al-Bukhari 2338—Umar expelled the Jews and the Christians from Hijaz. When Allah’s Messenger had conquered Khaibar, he wanted to expel the Jews from it as its land became the property of Allah, His Messenger, and the Muslims. Allah’s Messenger intended to expel the Jews but they requested him to let them stay there on the condition that they would do the labor and get half of the fruits. Allah’s Messenger told them, “We will let you stay on this condition, as long as we wish.” So, they (i.e., Jews) kept on living there until Umar forced them to go towards Taima and Ariha.
Ibn Ishaq, Sirat Rasul Allah, 515—Kinana b. al-Rabi, who had the custody of the treasure of B. al-Nadir, was brought to the apostle who asked him about it. A Jew came to the apostle and said that he had seen Kinana going round a certain ruin every morning early. When the apostle said to Kinana, “Do you know that if we find you have it I shall kill you?” he said Yes. The apostle gave orders that the ruin was to be excavated and some of the treasure was found. When he asked him about the rest he refused to produce it, so the apostle gave orders to al-Zubayr bin al-Awwam, “Torture him until you extract what he has, so he kindled a fire with flint and steel on his chest until he was nearly dead. Then the apostle delivered him to Muhammad bin Maslama and he struck off his head, in revenge for his brother Mahmud.
The History of al-Tabari, Volume 39, 185—While the Prophet was lying with Safiyyah, Abu Ayyub stayed the night at his door. When he saw the Prophet in the morning, he said, “Allahu Akbar.” He had a sword with him; he said to the Prophet, “O Messenger of Allah, this young woman had just been married, and you killed her father, her brother, and her husband, so I did not trust her (not to harm) you.”
Ibn Sa’d, Kitab al-Tabaqat al-Kabir, Volume II, 252—The Apostle of Allah sent for Zaynab Bint al-Harith [that’s the woman who poisoned him] and said to her: What induced you to do what you have done? She replied: You have done to my people what you have done. You have killed my father, my uncle, and my husband, so I said to myself: If you are a prophet, the foreleg will inform you; and others have said: If you are a king, we will get rid of you.
Sunan Abu Dawud 4498—A Jewess presented [Muhammad] at Khaibar a roasted sheep which she had poisoned. The Apostle of Allah ate of it and the people also ate. He then said: Lift your hands (from eating), for it has informed me that it is poisoned. Bishr died. So he (the Prophet) sent for the Jewess (and said to her): What motivated you to do the work you have done? She said: If you were a prophet, it would not harm you; but if you were a king, I would rid the people of you. The Apostle of Allah then ordered regarding her and she was killed.
Sahih al-Bukhari 2588—Aisha said, “When the Prophet became sick and his condition became serious, he requested his wives to allow him to be treated in my house, and they allowed him. He came out leaning on two men while his feet were dragging on the ground.”
Sunan Ibn Majah 1622—Aishah said: “I never saw anyone suffer more pain than the Messenger of Allah.”
Sahih al-Bukhari 4428—The Prophet in his ailment in which he died, used to say, “O Aishah! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison.”
