الشفاء بتعریف حقوقِ مصطفیٰ ﷺ کا تعارفی و تجزیاتی مطالعہ An Analytical Study of the “Al-Shifā Ba Ta‘rīf-e-Ḥuqūq-e-Muṣṭafā”

The most prominent and living name among the African biographers is Qazi Ayaz Mālkī. His book “Al-Shifā Ba Ta‘rīf-e-Ḥuqūq-e-Muṣṭafā” has an important place in the books of Sīrah and also has the status of the most popular book among all kinds of people. This book is also called Kitab-e-Shifā (meaning the one who revives hearts and heals from heart diseases). The reason for writing this book was that the people were becoming oblivious to the obligatory status and virtues of the Holy Prophet ﷺ and were becoming completely incapable of paying their dues. In these circumstances, the demand for preparation and compilation of a collection of rights and manāqibs related to it became intense and he compiled this magnificent book. On the one hand, it teaches love and respect for the Prophet (peace and blessings of Allah be upon him) and on the other hand, it mentions his rights and rewards for fulfilling them. The writing style of the book is simple and smooth as well as eloquent. The book is not so long that it would be too long for the reader to comprehend, nor is it so short that it would not be possible to get access to the concepts and demands due to its brevity. The people have made this book their favorite and have been studying it and the biographers have adopted Al-Shifā as an authoritative and reliable source. Because of its importance and usefulness, an introductory and analytical study of this book will be presented in this article.

Study of Collapsing Models in Theories of Gravity

In this thesis, collapsing models have been studied in different theories of gravitation. In particular, we have explored the Phenomenon of collapse in general theory of relativity, f(R) theory and f(R,G) theory. Firstly, we discuss the collapsing models in the framework of general theory of relativity. The collapsing model of charged anisotropic fluid with positive cosmological constant in four dimensions is addressed. It is noted that in the presence of electromagnetic field the collapsing rate is faster. When the fluid remains anisotropic and the electric field strength E0(t,r) vanishes, our investigations are in full agreement with the results obtained by Ahmad and Malik [59]. We also address five dimensional collapsing model with anisotropic pressure and positive cosmological constant and found exact analytic solutions to the field equations. We found that the area of cosmological horizon and black hole horizon has larger area in five dimensions than four dimensions. The shear-free gravitational collapse with heat flux is discussed by considering higher dimensional spherically symmetric spacetime as interior metric and higher dimensional Vaidya spacetime as exterior metric. The effects of dissipation on collapse are investigated. A simple approximate higher dimensional conformally flat model is proposed that satisfies the junction conditions. Temperature profile of the proposed model is also calculated. It is concluded that dissipation decreases the collapsing rate and temperature profile of the suggested model. We investigate higher dimensional spherically symmetric anisotropic collapsing solutions of the field equations, and to check the effects of higher dimensions on the density and pressures profile of the collapsing fluid. We have also studied the effects of higher dimensions on the dimensionless measure of an isotropy. Secondly, we study gravitational collapse of a perfect fluid in f(R) theory. We have solved the field equations by assuming linear equation of state (p = ωµ) with ω = −1. We have also discussed formation of apparent horizon and singularity. It is shown that singularity does not depend on the radial coordinate r, and is thus non central, that is, it can take place at all points simultaneously. The dynamics of spherical perfect fluid collapsing model with heat flux is investigated in f(R,G) gravity. For this purpose, we adopt the MisnerSharp formalism to construct the dynamical equations and drive transport equation. Furthermore, we examine the collapsing rate by coupling the transport and dynamical equations. It is noted that for constant f(R,G) model the collapsing rate reduces.
