مظاهر الرحمة في شخصية الرسول

Those who abused the Prophet r, and accused him of violence, slander and falsely, had never listened to the call of the mind. They should never ignore the one of the most important verses of the holy book revealed from the Creator, Allah Almighty, that Prophet Muhammad r has been sent to the mankind purely for offering mercy. How can they neglect the fact that the Prophet r himself said if he was a leader without mercy, people around him did not accompany him. When we study the life of Prophet r, we observe that all factions of the society, whether they are slaves or independent, Muslims or non- Muslims, men or women, beloved friends or worst enemies; they were behaved not only with extreme justice, but with utmost mercy. So we find that it was a mercy in everything, in education, in advocacy and in legislation, in war and peace, in the family and society, and in all walks of life, etc. In this article, aspect of mercy in the personality of holy Prophet Muhammad r has been discussed in detail. Opinions of the Orientalists are also presented in the article. Aspect of mercy was not only an ingredient of the personality of Prophet r, but He r also made mercy a part of his followers’ personalities. So history witnesses that there was an elongated reign of peace in the world, whenever Muslim Rulers were in power.

Boundary Layer Flows of Modified Second Grade Fluid over Stretching Surfaces With Heat Transfer

The study of boundary layer flows of non-Newtonian fluids is an important and challenging task in fluid mechanics. The recent decades saw a lot of interest in this area because of the fact that many important industrial fluids are non-Newtonian in their flow characteristics. The main aim of this thesis is to explore and analyze the boundary layer flow with heat transfer of a non-Newtonian fluid. Thus, this thesis revolves around one of the paramount subclass of non-Newtonian fluids namely the modified second grade fluid (MSGF). Despite of the diverse applicability of this fluid model in technological fields, not much study has been made on flow and heat transfer characteristics of MSGF. In view of this, the research presented in this thesis is carried out to fill up the existing gap in literature. Boundary layer equations for the flow and heat transfer of modified second grade fluid are bestowed in Cartesian as well as cylindrical polar coordinates. Additionally, the non-linear stretching surfaces are investigated keeping in view different geometries like stretching cylinder, radially stretching sheet and planar stretching sheet. Numerous effects of flow and heat transfer are incorporated namely the stagnation point flow, magnetohydrodynamic (MHD) flow, nanoparticles, mixed convection heat transfer, linear and non-linear thermal radiation, homogeneous-heterogeneous reactions, Newtonian heating and convective boundary conditions. The governing problems comprising of highly non-linear partial differential equations are simplified by suitable transformations into the corresponding ordinary differential equations. The resultant systems of equations are numerically handled by the Runge-Kutta Fehlberg scheme and bvp4c in MATLAB. The legitimacy of the numerical results is ensured by presenting a comparative study for special cases. The graphical and tabular illustrations are displayed for various pertinent parameters to obtain the physical insight of the problem. In addition, exact solutions are also calculated for few problems by considering special cases. One of the key observation is that the generalized second grade parameter strengthens the fluid velocity while diminishes the temperature of the fluid.
