Human life is constantly evolving and technology helps with the advancement. In many Muslim societies such as in Malaysia, halal and haram issue is a sensitive concern not only not only with regard to foods but also medical materials and devices. Many medical issues highlighted involve the use of drugs mixed with non-halal materials or impurities such as pigs, carcasses and corpses. The use of drugs is also an issue in the field of dental treatment such as Biogide®, EmdoGain® and Bio-Oss®. The absence of a fiqh principle model for dental treatment, especially involving these materials complicates doctors’ treatment of patients in order to know whether these substances are authorized by Islamic rules or otherwise. This study analyses guidelines used in the application of drug and medical devices derived from non-halal materials. The approach used in this study is based on a study of the Quran, Sunnah, views of the Ulama' and the analysis of contemporary fatwas. The results show that the use of non-halal devices in dental treatment is prohibited except in emergencies. The use of non-halal materials is also prohibited if the recovery is medically dubious. Advice of pious Muslim doctors is also demanded before treatment.

The theory of the actual employee aims at preserving the considered interest of the bona fide third party with his dealings with the administrative authorities, and not preserving the interests of those authorities or the employees themselves as usual in the laws. The Palestinian legislation did not address this theory and there is a difference between the actual employee and the actual government, where employees are considered The latter are legal employees with full competence and authority, and there are no real applications of the theory of the actual employee in the Palestinian judiciary, whether in Gaza or the West Bank, as the theory does not apply to most emergency practical cases in the Palestinian case that result from the hateful political division. This study recommends that the administrative judiciary should pay attention to the work of this theory whenever the good faith interest of others requires it. It also recommends not to cite this theory regarding the employees of Gaza after the division, as it does not apply to them on the one hand, and on the other hand, it does not help them in obtaining their rights as official employees. Directing graduate students to research this theory with their theses. And intensify research and awareness on administrative theories appropriate to the exceptional Palestinian situation.
