104. Al-Humazah/The Slanderer
I/We begin by the Blessed Name of Allah
The Immensely Merciful to all, The Infinitely Compassionate to everyone.
104:01
a. Woe to every slanderer and backbiter,
104:02
a. as also the one who amasses wealth without spending a part of it on charity, and keeps
adding and counting it over and over again,
104:03
a. thinking - in his ignorance - that his wealth will make him live forever.
104:04
a. Never!
b. It is not like what he thinks.
c. On the contrary, he will certainly be flung into the Crushing Fire - that which breaks its inmates to pieces.
104:05
a. And what may enable you to comprehend the Crushing Fire?
104:06
a. The Crushing Fire is Allah’s Fire, fiercely set ablaze,
104:07
a. which will leap up and penetrate deep into sinful peoples’ hearts and shall burn within as without.
104:08
a. It will definitely be closing upon them from all directions,
104:09
a. in towering and extending columns of flames.
In Western, countries there is a great fear of Islam and Muslims leading to a great hatred which in turn makes them think that Islam is a religion of violence that it allows the massive killing of people. After the incident of 9/11, Islamophobia has taken another turn. In this regard, it is the utmost duty of every Muslim to find the solution to this problem collectively as well as individually. It is therefore necessary, to think of a solution which favors the teachings of Islam without harming the humanity. It is a pressing need of the day that the true picture of Islam be brought forth through practice upon Shariah. We as muslims should play our role in changing the perception of our religion as the religion of ‘peace’ and preserver of humanity.
This work presents new results regarding the behavior of some non-Newtonian fluids into different circumstances. After some preliminaries regarding constitutive equations, motion equations and integral transforms, new exact solutions for the ve- locity field and the shear stress corresponding to some flows with technical relevance have been established for ordinary second grade, Oldroyd-B fluids and generalized Maxwell fluids. Just as in the case of Navier-Stokes fluids, it is necessary to develop a large class of exact and approximate solutions, they serving as tests to verify nu- merical schemes that are developed to study complex unsteady flow problems. In chapter 2, by means of the Laplace transform, there are established new exact solutions corresponding to the first problem of Stokes for Oldroyd-B fluids. These solutions, in accordance with the previous results obtained using Fourier sine trans- form, can be easily specialized to give similar solutions for Maxwell fluids. The main aim of chapter 3 was to solve a very important problem, namely to determine the re- quired time to reach the steady-state for the second problem of Stokes corresponding to second grade fluids. In addition to solve this problem we also found new exact so- lutions for this problem. Our solutions, unlike the solutions obtained by Erdogan for Newtonian fluids, are written as a sum between steady state and transient solutions. Chapter 4 contains exact solutions for the unsteady flow of an Oldroyd-B fluid between two side walls perpendicular to a plate. In the absence of side walls the obtained solutions tend to the similar solutions for the flow over a flat plate (the first problem of Stokes). The influence of the pertinent parameters on the velocity of the fluid at the middle of the channel as well as on the shear stress on the bottom is underlined by graphical illustrations. In chapter 5, by means of Laplace and Hankel transforms, we obtained the solutions for unsteady flow of a generalized Maxwell fluid between two circular cylinders. These solutions, presented as a sum of the Newtonian solutions and the non-Newtonian contributions, can be easily specialized to give the similar solutions for ordinary Maxwell fluids. Finally, the influence of the pertinent parameters on the velocity of the fluid are also underlined by graphical illustrations.
