They also found with it a string with eleven knots knitted with needles. Allah, exalted is He, then revealed Surah al-Falaq and Surah al-Nas (al-Mu'awwidhatayn). With each verse that the Messenger of Allah, Allah bless him and give him peace, read one knot was untied and the Prophet, Allah bless him and give him peace, felt some lightness. When the last knot was untied, the Prophet, Allah bless him and give him peace, got up as if he was released from a cord to which he was tied up. Gabriel, peace be upon him, kept saying: 'In the name of Allah I cast this incantation on you to protect you from anything that might harm you and that Allah heals you from the resentful envier and the evil eye'. Those around him said: 'O Messenger of Allah, should we not head toward that evil person and kill him?' He said: 'As for me, Allah has cured me, and I dislike causing evil to other people'. This is of the forbearance of the Messenger of Allah, Allah bless him and give him peace”. Muhammad ibn 'Abd al-Rahman ibn Muhammad ibn Ja'far informed us> Abu 'Amr Muhammad ibn Ahmad al-Hiri> Ahmad ibn 'Ali al-Mawsili> Mujahid ibn Musa> Abu Usamah> Hisham ibn 'Urwa> his father> 'A'ishah, may Allah be well pleased with her, who said: “A spell of black magic was cast on the Prophet, Allah bless him and give him peace, such that he used to imagine that he did things when he did not. He was at my place, one day, and he began imploring Allah in earnest. Then he said: 'Did you not feel, O 'A'ishah, that Allah has answered me about that which I have enquired?' I said: 'And what is that, O Messenger of Allah?' He said: 'Two angels came to me…', and he mentioned the whole story”. The whole story is narrated by Bukhari from 'Ubayd ibn Isma'il from Abu Usamah. The same narration has different channels of transmission in both the authentic collections of Bukhari and Muslim. The book Asbab Nuzul al-Qur'an concludes here, and praise be to Allah, the One, the Munificent, and may Allah bless our master Muhammad, his household and all those who follow them in excellence.
