Answered by Shaykh Abdurrahman ibn Yusuf Mangera
The scenario is that a brother had his a large amount of his property stolen from him and so he approached another brother about reclaiming this property. To which he was asked for his name and his mothers name and it was inscribed on a sheet with Arabic text. It was then folded by the aiding brother who advised to place it underneath a heavy object. When the victim of the crime asked about what would happen, he was told that the thief would receive bleeding and continuous vomiting which no-one could relieve until he returned the property. Is this permitted in the Islamic Shariah and if so what is the daleel for or against it with references to established opinions in the Hanafi madhab. This issue is very urgent as it is causing great fitna in the local community,
In the name of Allah, the Inspirer of truth.
We should not resort to practices of this nature, since it does not provide certitude [yaqin] or concrete proof on any case. Those who use these methods, in many cases employ the service and help of jinns. It is established that only Allah has complete knowledge and command of the unseen. The jinn do not have knowledge of all hidden affairs. Allah states regarding the jinn at the time of the demise of Sulayman, that had they possessed the knowledge of the unseen, they would not have had to remain for so long enduring the strains of the construction work Sulayman had ordered them to do.
Furthermore, if practices of this nature ever reveals the true criminal, that would only be considered a coincident. Many times such practices have caused great dissent and conflict in families and communities.
Maulana Ashraf Ali Thanwi has written that whatever is revealed through such methods needs to be verified though the proper Islamic way of ascertaining the truth of an issue. These practices do not provide certitude. However, since most people utilize these methods with full faith in them and take them to be definite, such methods would be considered prohibited and people should abstain from them. (Imdad al-Fatawa 4:88)
And Allah knows best.

[Shaykh Faraz Rabbani adds: Another problem with this is the use of magic, and the scholars note that it is impermissible to invoke jinns on others, especially believers, and that one must confine one’s retribution against others to the limits laid down by the Sacred Law.]
