اسلامی اور مغربی تناظر میں آزادی اظہار رائے کا تقابلی جائزہ

Freedom of Expression: A Comparative Study from Islamic & Western Perspective Living on the earth is all about freedom and as we know that the first man on the earth Adam was sent on the earth with the freedom to worship only to Allah. This freedom is a blessing of Allah and the value of it would only be judged in the era of slavery. It is an ultimate principle in Islam that the total submission is to be Allah alone. Thus, a man would never be a slave of any other person and whenever they become a slave to any other authority they are treated inhumanly. Allah (SW) made this glorious world for human beings and granted them the status of Ashraf ul Makhlūq. Human has such value which can be testified by this reason that everything is tightened to them and the world is only created for them. But human can only be benefited from the world till they are better for them and others, living friendly and create atmosphere of peace. So, till the end they will be benefited and blessed. They will also be in peace and freedom if they take care and have the respect for humanity. As man is a social animal and doesn’t live without his community. Sometimes due to controversy in thinking and other routes fall in conflicts, for which a proper law is administered. The differences in views are not forbidden. It is important, not to cross limits and to create peaceful atmosphere in order to rest humanity in peace and make the world peaceful. This article deals with the comparison of Islamic freedom of expression and the modern Western criterion of freedom of speech. The study concludes that the Islamic and western thought on freedom is different from each other.  In this study comparative and critical approach is adopted.

Ab-Initio Investigation of Pristine and Intrinsic Vacancy Defect-Containing A3sno and A3pbo A: Ca, Sr and Ba Inverse Perovskites

The A3SnO and A3PbO (A: Ca, Sr and Ba) inverse perovskite oxides have gained immense research attention as they exhibit physical properties suitable for thermoelectric, superconducting and magnetic devices. The emergence of stoichiometry dependent stable ferromagnetism in these inverse perovskites has recently made these materials potential candidates for utilization in spintronic and quantum computing devices. In the present work, DFT based first principles total energy calculations have been employed using the full-potential linearized augmented plane-wave method to explore the electronic, magnetic and thermodynamic properties of pristine and intrinsic vacancy defect containing A3SnO and A3PbO (A: Ca, Sr and Ba) compounds. The electronic structures of these compounds are computed with the inclusion of spin orbit coupling interactions which plays an important role in topological nature of these compounds. Furthermore, the spin-polarization calculations have been carried out to investigate the impact of vacancy defects on magnetic and electronic properties of these inverse perovskites. The thermodynamic stability analysis indicated that these materials can be synthesized under Ca/Sr/Ba rich and Sn/Pb intermediate-rich conditions. Moreover, the defect formation energies revealed that Ca/Ba/Sr vacancies are the most stable form of vacancy defect under oxidation (O-rich) conditions, while O and Sn/Pb vacancies are found to have stableunder reduction (O-poor) and Sn/Pb-poor conditions, respectively. Our calculations reveal that charge neutral Sn or O vacancies can give rise to stable ferromagnetism in non-stoichiometric A3SnO and A3PbO (A: Ca, Sr and Ba) compounds.
