I remember an old person from my mother's hometown. He was some Peer or Murid, I guess. He always wore Black Kurta with a white Izaar and a green turban. He was close to my maternal relatives. Whenever he visited us, if I happened to be around, he used to call me by his side and pass his hand through beard and miraculously get me some peanuts or peppermints with a friendly smile. When I asked "how did you do that?", he never said anything. When I asked my mother about it, she told me that he possessed (Has control over) some Jinns and by running hand through his beard, he makes some gestures to the Jinns and they obey it. I was less than 8 then.
Slowly, after years went by, I started thinking that he had tricked me by hiding substances in his long beard and tricks all the people in this way and has no control over Jinns. I strongly believed that he was a trickster until I was around 15 when I happened to be around him once again. He had grown weak. As I was not a little boy, meeting him was just a matter of Salaam and no peanuts or peppermints. This time he was thirsty, and asked my cousin for a glass of water. She (my cousin) said to him: "Why don't you get a lemon? I'll prepare some sweet lemon water for you.". Nodding his head in agreement he again ran both his hands through his beard and believe me, there was a lemon in his hand. I was watching this and am sure that before running his hand through his beard, he had nothing in his hand. Also, if he was a trickster how could he get nothing other than lemon? I mean, To test him, people may ask him to get anything at anytime just like my cousin did. It is impossible to carry everything in a beard.
Though I can remember only these two instances, many people in the town (Tiptur in Karnataka state of India) have similar stories to say. Unfortunately, Khaleel Hazrath(The old man) met with a train accident a few years back and is no more.
In the long story, one thing might be clear to you: I cannot disbelieve what I have seen with my eyes. But, In no way I am forcing anyone to believe. So maybe Allah has proved to me that this kind of magical stuff can happen. But is this stuff usual?, In the history (other than that of Prophets) and scriptures of Islam, has such a thing ever been witnessed? and most importantly, Can Jinn be possessed (If possessed is not the right word, Controlled) by a human?
We have heard of stories like Messengers of Allah (especially Sulaiman [pbuh]) could order Jinns. But Khaleel Hazrath was a common but a pious man, maybe he was a Hafiz (not necessarily) because I have seen him teaching Qur'an to children.
