3۔اندھا بوڑھا

اندھا بوڑھا

نعمان نذیر

صبح ہوتے ہی  معمول سے کچھ دیر پہلے ہی اس کی آ نکھ کھل گئی ۔ یوں تو وہ آ غاز سے ہی اپنے کام میں مہارت کے ساتھ ساتھ وقت کی پابندی کا بھی قائل تھا۔ شاید ہی ان دس سالوں میں کھبی اس کو افسران بالا کی طرف سے اس بات کا اعتراض کیا گیا ہو کہ وہ وقت پہ دفتر نہیں پہنچا ۔ ان دس سالوں میں اس کے افسر جو متعدد تبدیل ہو چکے تھے۔ کوئی بھی اس کے کام پہ معترض نہ تھا۔۔۔۔۔۔۔

آج اس کی زندگی کا ایک اہم دن تھا۔ اس موقع پہ اس کی بیوی بھی اس کی خوشی میں برابر شریک تھی۔ اسی کی خدمت اور حوصلے سے تو وہ آ ج اس مقام تک پہنچا تھا۔۔۔۔۔۔۔۔

اس خبر کا انتظار اسے گزشتہ دو سال سے تھا ۔ وہ مسلسل اپنی محنت کا پھل پانے کے لئے آ ج تیار تھا ۔ یہ دن تھا اس کی محکمانہ ترقی کا۔۔۔۔۔

اس خبر کی اطلاع تو اسے نیم کلرک نے ایک مہینہ قبل ہی دے تھی۔ جب اس کی ترقی کا پروانہ مرکزی دفتر میں دستخط ہونے کا منتظر تھا۔ ۔۔۔

اس موقعہ کو یاد گار جانتے ہوئے اس نے نیا قیمتی لباس بھی تیار کروایا تھا ۔ گزشتہ اتوار کو وہ اپنی اہلیہ کے ہمراہ شہر کے سب سے بڑے شاپنگ مال میں کپڑے اور جوتے خریدنے گیا ۔ اس کی بیوی نے اپنے خرچ میں سے جمع کی گئی رقم سے مہنگے جوتے خرید کر تحفہ دیا۔ جو اس کی اس کامیابی کو اپنی کامیابی سمجھتی تھی ۔۔۔۔۔

آ خر کار 15 ستمبر کے دن کا سورج طلوع ہوگیا ۔ وہ معمول...

سیدہ زینب ؓ کا رسول اللہﷺ سے نکاح اور مستشرقین

Many western scholars have tried to interpret the Holy Qur’an into other languages of the world. William Montgomery Watt and Robert Spencer are included in the list of those commentators of the Qur’an who have presented their Quranic commentary in English language. But while interpreting the verses of the Holy Qur’an about the life, character and teachings of the Holy Prophet both the scholars have fabricated the teachings of the Holy Qur’an. Therefore, the main purpose of this study is to compare and analyze the interpretation of both western writers about the verses of Sūrah al-Aḥzāb in which the necessary information about the marriage of Prophet Muhammad with Hazrat Zainab has been discussed. Through the text analysis method and comparative and analytical approach, this article has raised some of the errors and propaganda elements found in the commentaries of both the Western scholars. The article proves that the writings of Western scholars like this need to be refined and scrutinized carefully in maintaining the sanctity of Islam and respecting the rights of the Prophet Muhammad (PBUH). This paper concludes that all such allegations are either based on fabricated historical reports or false interpretations and misunderstanding of the facts.

Numerical Solutions of Unsteady Models of Non-Newtonian Fluids

The aim of this thesis is to examine the unsteady effects in the two or three dimensional boundary layer flow of non-Newtonian fluids along with the presence of different physical factors. Heat and mass transfer is involved with first order chemical reaction. In some cases, soret and dufour effects are also investigated. The flow models are explained in terms of continuity, momentum, energy, concentration equations which are converted into dimensionless form by using similarity transformation. Solutions are then obtained by an analytic-numeric technique Homotopy analysis method (HAM) and then comparison is shown by using Runge-Kutta-Fehlberg algorithm with shooting method. Convergence of solution and graphs of error analysis are also included to check the authenticity. Study of motion of the fluid’s behavior with heat and diffusion processes are depicted vividly through graphs and tables against different pertinent parameters. It is observed that magnetic force always slows down the velocity rate and presence of Casson and Maxwell parameter enhances the thermal and solute boundary layer as compared to the steady model. In Chapter 2, an endeavor is applied to observe the approximate solutions of unsteady two-dimensional boundary layer flow with heat and mass transfer behavior of Casson fluid past a stretching sheet in presence of wall mass transfer and 1st order chemical reaction. After adopting the similarity transformation; Homotopy analysis method (HAM) is applied to solve these ordinary differential equations. Numerical work is done carefully with a wellknown software MATHEMATICA for the examination of non-dimensional velocity, temperature, and concentration profiles, and then results are presented graphically. It is observed that involvement of time dependent factor reduces the thermal but enhances the solute boundary layer as compared to the steady model. v The Chapter 3 is useful to investigate the analytic-numeric solutions of an unsteady 3-D MHD Casson fluid flow which is embedded in a porous medium past a stretching sheet under the heat transfer influence. The similarity transformation is adopted to convert the partial differential equations of current model into its dimensionless form. Then, it is solved by employing an algorithm of a powerful technique Homotopy analysis method (HAM). After that, solutions are compared by invoking Runge-Kutta based shooting method. The theme of Chapter 4 is to study the first-order chemically reacting Maxwell fluid past a stretching sheet embedded in a porous medium with the discussion of wall mass transfer and Soret, Dufour effects. HAM is invoked on the dimensionless form of flow model for the series solution; where numerical simulation is carried out by a powerful software MATHEMATICA. Furthermore, the impact of disparate physical parameters on the flow, temperature and concentration profiles are shown vividly. Errors graphs are also there to show the authenticity of results. At the end, in Chapter 5, a precise note or conclusion related to whole of my thesis is provided.
