Q: I read a book entitled "A Conversation with a Jinn" by Usamah Al-Karm. I would like to confirm the authenticity of what was mentioned in page 899 entitled: A message that tortures Jinn.The great Sahaby (Companion of the Prophet) Abu Dujanah said, "I told the Messenger of Allah (peace be upon him) that when I was lying on my bed, I heard a noise like that of a millstone, a buzz like that of bees, and I saw a glare like that of lightning. I was startled, then I saw a black shadow in the hall of my house. When I touched it, I felt its skin like that of a hedgehog. It blew fire at me, and I thought my house was going to be burnt. The Messenger of Allah (peace be upon him) said, "You have been afflicted by an evil guest, Abu Dujanah. By Allah, such a man like you cannot be hurt, Abu Dujanah." He then said, "Give me a paper and a pen." He gave them to `Aly ibn Abu Talib and said to him, "Write, Abu Al-Hasan." He asked, "What shall I write?" He (peace be upon him) said, "Write: In the Name of Allah, the Most Gracious, the Most Merciful. This is a letter from Muhammad the Messenger of Allah to the visitors who knocked on (Part No. 24; Page No. 242) the door. Both you and we are protected by the truth. Whether you are an ardent lover, an impudent intruder or a claimer of a false right, our record speaks about you in truth. Indeed, We are transcribing whatever you do, and our Messengers (angels) record what you conceal. Leave the owner of this message and go to those who worship idols or those who claim another Ilah (God) with Allah. There is no Ilah other than Him; everything will be destroyed except His Face. His is the judgment, and to Him you will return and be overcome. Ha-Mim, you will not be helped. Ha-Mim, `Ain-Sin-Qaf. The enemies of Allah will be scattered, and the evidence of Allah is established. There is neither might nor power except with Allah! He will suffice you against them; He is the All-Hearer, the All-Knower."Abu Dujanah said, "I took this letter home, put it under my pillow and slept. I only woke up to the scream of someone saying, 'O, Abu Dujanah! We are burnt by these words. By the truth of your companion (the Prophet), if you take this letter away, we will return neither to your house nor to the neighbors' or any place where this letter is.' Abu Dujanah said, "No, by the truth of the Messenger of Allah (peace be upon him), I will not take it off until I ask him." He continued, "My night was made so long by the screams of Jinn. In the morning, I offered the Fajr (Dawn) Prayer with the Messenger of Allah (peace be upon him), and told him what happened. He then told me, 'O, Abu Dujanah! Be merciful with them. By Him who sent me with the truth, they will suffer until the Day of Judgment.'" Narrated by Al-Bayhaqy (Part No. 24; Page No. 243) in "Dala'il Al-Nubuwwah" (7/120) and related also by Al-Suyuty .Is this tale true? May Allah reward you.
