سیرت طیبہ پر استشراقی فکر کے اعتراضات کے اسباب و عوامل کا تاریخی و ارتقائی جائزہ

Over the course of time and with the rapid increase in human population need for mutual relations become crucial. Resultantly on behalf of this closeness, separation, anti-standpoints and comparisons also emerged. As the time passed by hatred and hypocrisy and other social vices spread on large scale. Thus human society was waiting for such liberator who may lead and work for the betterment of this society. With the dawn of Islamic civilization all such issues were not only resolved but also provided with a model for containing the difference of opinion and multiple traditions under its unique worldview. Islamic History presents itself as a model where the minorities were provided with the opportunities of participating in political, social, educational and collective affairs. Thus in a society where tyranny, injustice, un-forbearance, religious intensity, terrorism and the activities of violating the human rights were very common, were substituted by the Islamic ideal  of forbearance. It is argued here that the solution of all these issues was only in religion contrary to what is being claimed about an idea of social harmony where religion is not given its due position. Today its our dire need to develop a sense of harmony, modesty, affection and peacefulness among the masses of various religions of Pakistani society. It is further argued that for this very noble cause all the religious scholars and their followers can come forward playing their pertinent role.  

Stability Analysis of Self-Gravitating Collapsing Systems

This thesis deals with the dynamical instability as well as inhomogeneities in self- gravitating collapsing objects. For this purpose, the matter distribution is considered imperfect due to anisotropic pressure, shear and bulk viscosity, dissipation in di®usion and streaming out limits and electromagnetic e®ects. For instability regimes, the interior region is taken as spherical, cylindrical and axially symmetric spacetimes which are matched with suitable exterior to explore Darmois conditions. The ¯eld equations and conservation laws are formulated and then perturbed up to ¯rst order in perturbation parameter to construct the collapse equation. The instability regimes are investigated under both N and pN approximations. A crucial role of adiabatic index has been analyzed in the presence of expansion scalar. For spherical con¯guration, the matter distribution is considered to be charged anisotropic dissipative with shear viscosity. The charged cylindrical geometry is dis- cussed with three types of °uid con¯gurations. In the ¯rst case, we take anisotropic pressure, bulk viscosity and dissipation only in di®usion approximation. The second case studies the instability epochs with anisotropic pressure under zero expansion con- dition while in the third case we take isotropic °uid with dissipation in streaming out limit. The dynamical instability for axially symmetric geometry includes two kinds of matter con¯gurations. Initially, this analysis is done only with anisotropic matter, but later we discuss the role of heat °ux and shear viscosity as well. We conclude that the radial pro¯le of material variables like energy density, principal stresses, dissipation, viscosity and electric charge control the stability of self-gravitating objects. The inhomogeneity factors have been identi¯ed for charged plane symmetric space- time with some particular cases of non-dissipative and dissipative °uids. In the non- dissipative case, we analyze inhomogeneity factor for dust, isotropic and anisotropic matter distributions while dissipative matter distribution includes only geodesic dust °uid. We ¯nd that electric charge increases inhomogeneity in the energy density, which is due to shear scalar, anisotropy and dissipation. Also, we explore some dynamical variables, structure scalars as well as an explicit expression for the super- Poynting vector associated with tilted and non-tilted Szekeres spacetime.
