Moreover, peace is the most fundamental value in the Qur'an and Islam. The majority of the classical Muslim jurists, especially Hanafi school, emphasised that the reason for Muslims' fight against non-Muslims is Muslims' defense themselves against attacks, not non-Muslims' faith. Bediuzzaman Said Nursi (d. 1960) states that the only kind of jihad that is appropriate for the present age is spiritual or moraljihad. Furthermore, regarding Qur'anic approach to relations between Muslims and the People of the Book, Muslim scholars, in general, advocate sincere relations and trust between Muslims and the People of the Book. In addition, Said Nursi is one of the great Muslim scholars in interfaith dialogue in the 20th century. Finally, there is the need for establishing culture of coexistence, which practised before within a religious tradition such as Islamic tradition for many centuries in the history. Through achieving a culture of coexistence and peace, most conflicts can be resolved.展开更多

The multi-layered composites were 6 mm thick and each consisted of a 2 mm thick layer of recycled α-Fe<sub>2</sub>O<sub>3</sub>/PCL composites at various loadings (5 wt% - 25 wt%) of 16.2 nm recycled α-Fe<sub>2</sub>O<sub>3</sub> nanofiller, placed between two layers of 2 mm thick OPEFB fiber/PCL composites blended at a fixed ratio of 7:3. The real (ε') and imaginary (ε") components of the relative complex permittivity were measured using the open-ended coaxial probe technique and the values obtained were applied as inputs for the Finite Element Method to calculate the reflection coefficient magnitudes from which the reflection loss (RL) properties were determined. Both ε' and ε" increased linearly with recycled α-Fe<sub>2</sub>O<sub>3</sub> nanofiller content and the values of ε' varied between 3.0 and 3.9 while the ε" values ranged between 0.26 and 0.64 within 1 - 4 GHz. The RL (dB) showed the most prominent values within the 1.38 - 1.46 GHz band with a minimum of -38 dB attained by the 25 wt% composite. Another batch of minimum values occurred in the 2.39 - 3.49 GHz range with the lowest of -25 dB at 2.8 GHz. The recycled α-Fe<sub>2</sub>O<sub>3</sub>/OPEFB fiber/PCL multi-layered composites are promising materials that can be engineered for solving noise problems in the 1 - 4 GHz range.展开更多
