Sahih Bukhari Volume 8, Book 73, Number 81:


Narrated Ibn 'Abbas:

Once the Prophet went through the grave-yards of Medina and heard the voices of two humans who were being tortured in their graves. The Prophet said, "They are being punished, but they are not being punished because of a major sin, yet their sins are great. One of them used not to save himself from (being soiled with) the urine, and the other used to go about with calumnies (Namima)." Then the Prophet asked for a green palm tree leaf and split it into two pieces and placed one piece on each grave, saying, "I hope that their punishment may be abated as long as these pieces of the leaf are not dried."

Narrated Abu Musa:

The Prophet heard a man praising another man and he was exaggerating in his praise. The Prophet said (to him). "You have destroyed (or cut) the back of the man."

Sahih bukhari:Volume 8, Book 73, Number 89:


Narrated 'Aisha:

The Prophet continued for such-and-such period imagining that he has slept (had sexual relations) with his wives, and in fact he did not. One day he said, to me, "O 'Aisha! Allah has instructed me regarding a matter about which I had asked Him. There came to me two men, one of them sat near my feet and the other near my head. The one near my feet, asked the one near my head (pointing at me), 'What is wrong with this man? The latter replied, 'He is under the effect of magic.' The first one asked, 'Who had worked magic on him?' The other replied, 'Lubaid bin Asam.' The first one asked, 'What material (did he use)?' The other replied, 'The skin of the pollen of a male date tree with a comb and the hair stuck to it, kept under a stone in the well of Dharwan."' Then the Prophet went to that well and said, "This is the same well which was shown to me in the dream. The tops of its date-palm trees look like the heads of the devils, and its water looks like the Henna infusion." Then the Prophet ordered that those things be taken out. I said, "O Allah's Apostle! Won't you disclose (the magic object)?" The Prophet said, "Allah has cured me and I hate to circulate the evil among the people." 'Aisha added, "(The magician) Lubaid bin Asam was a man from Bani Zuraiq, an ally of the Jews."
