پروفیسر شیخ عبدالقادر سرفراز (پونا)
ناسک (بمبئی) کے ایک خط سے جو مرحوم کے چھوٹے بھائی نے مجھے لکھا تھا یہ معلوم کرکے بڑا تاسف ہوا کہ میرے چالیس برس کے دوست پروفیسر شیخ عبدالقادر سرفراز نے پونہ میں اپنے مکان کا شانہ حق میں ۱۰؍ دسمبر ۱۹۵۲ء کو ساڑھے نو بجے انتقال فرمایا، اس کے بعد مرحوم کے بڑے صاحبزادے ڈاکٹر شیخ عبدالحق ایم، اے۔ پی، ایچ، ڈی پروفیسر اردو فارسی (بمبئی) کی اطلاع سے اور بہت سی باتیں معلوم ہوئیں، یہ بھی معلوم ہوا کہ مرحوم کو بڑھاپے اور شیخوخت کے ضعف کے سوا کوئی خاص مرض نہ تھا، بصارت سے معذور ہوچکے تھے، ایک ہفتہ سے ضعف بڑھتا جاتا تھا، ڈاکٹروں کے معائنہ سے قلب اور اعضائے رئیسہ توانا پائے گئے، حواس آخر تک بجا تھے، سوا نو بجے خود آنکھیں بند کرلیں لب ہل رہے تھے، غالباً کلمہ پڑھ رہے تھے، ۱۵ منٹ کے بعد یعنی ساڑھے نو بجے صبح کو اس دنیائے فانی سے سفر اختیار کیا۔
۱۹؍ جولائی ۱۸۷۹ء پیدایش کی تاریخ تھی، بہتر (۷۲) برس کی عمر پائی، مرحوم کا خاندان دراصل یوپی کا باشندہ تھا، غدر کے ایام میں بمبئی کی طرف نکل گیا، مرحوم کے والد شیخ سرفراز ڈاکٹر تھے، انہوں نے ناسک کو اپنا وطن بنایا لیکن مرحوم کی عمر کا بڑا حصہ پونہ اور بمبئی میں گزرا ۱۹۰۲ء میں بمبئی یونیورسٹی سے ایم، اے پاس کیا اور غالباً ان کا خاص موضوع فارسی تھا، اس زمانہ میں ایک شریف ایرانی فاضل پروفیسر مرزا حیرت بمبئی یونیورسٹی میں فارسی کے مسندنشین صدر تھے، ان کا غیر معمولی فضل و کمال تمام بمبئی میں مسلم تھا، مرحوم شیخ عبدالقادر کو فارسی کا ذوق انہی کی صحبت سے حاصل ہوا، چنانچہ مرزا حیرتؔ کی انہوں نے مختصر سوانح عمری بھی لکھی ہے اور مجلس میں اکثر ان کے فضائل...
In an Islamic state, the leader is obliged by the Quran to run the affairs of the people using ‘Shura’ (consultation). He is elected based upon confidence to lead, not on his policies, because he is obliged to derive laws based upon the Quran and Sunnah، and has no option to not implement the clear laws cont-ained therein, even if not convenient for gov, which provides full protections for people’s rights at all times. In a (Western) secular Democracy, the leaders are not obliged to consult the people in running the affairs (nor fulfil their promises). They derive laws from what is convenient, and may (and do) take away people’s rights using that justification. In Islam, the leader remains in power until he becomes unjust or incompetent. In a (Western) secular Democracy, the leader remains in power despite being unjust or incompetent, and may get elected again if he can lie to the people to persuade them he is the lesser of two evils. An Islamic State is based upon sovereignty to the Creator, who doesn’t change his mind, it not prone to prejudice, bigotry or ignorance. A (Western) secular Democracy is based upon sovereignty of the Individual, who does change their mind, is prone to prejudice, bigotry and ignorance. This article explains deeply about Comparison of Islamic concept of state and non Islamic Idea of State.
In this thesis some results regarding the flow behavior of second grade fluid with fractional derivatives and ordinary Oldroyd-B fluid under different circumstances have been studied. Firstly, some basic concepts regarding fluid motion and integral trans- forms have been discussed. Then the fluid motion of fractional second grade and ordinary Oldroyd-B fluids through a cylinder and annulus is studied. In chapter 2, the motion of fractional second grade fluid through an infinite cir- cular cylinder has been studied. After time t = 0+ the fluid motion is produced by rotating the circular cylinder about its axis. Laplace and finite Hankel transforms are used to find exact solutions. The similar solutions for Newtonian and ordinary second grade fluids are obtained as limiting cases of general solutions by making κ → 1 and α1 → 0, respectively κ → 1 . Chapter 3 intends to establish exact solutions for the unsteady flow of a fractional second grade fluid between two infinite coaxial circular cylinders. The general expres- sions for velocity and shear stress are obtained by using Laplace and finite Hankel transforms. The motion of the fluid is produced by the inner cylinder which is ro- tating around its axis due to a time-dependent torque per unit length 2πR1 at2 . The solutions that have been obtained satisfy all imposed initial and boundary conditions. For κ → 1, respectively κ → 1 and α1 → 0, the corresponding solutions for ordinary second grade and Newtonian fluids, performing the same motion, are obtained as limiting cases. In chapter 4 the unsteady helical flow of an Oldroyd-B fluid through an infinite circular cylinder is studied. The motion of the fluid is produced by cylinder that, after time t = 0+ , is subject to both torsional and longitudinal time dependent shear stresses. The general solutions are presented in series form in terms of Bessel functions J0 (•), J1 (•) and J2 (•), and satisfy all imposed initial and boundary conditions. The corresponding solutions for Newtonian, second grade and Maxwell fluids are obtained as limiting cases of general solutions. Finally, the obtained solutions are compared by graphical illustrations and the influence of material parameters on the fluid motion is also underlined. Chapter 5 concerns with the unsteady Taylor-Couette flow of an Oldroyd-B fluid in an annulus due to a time-dependent torque applied to the inner cylinder. Motion is studied by means of finite Hankel transforms. The exact solutions are presented in series form in terms of usual Bessel functions, satisfy both the governing equations, and all imposed initial and boundary conditions. Similar solutions for Newtonian, second grade and Maxwell fluids performing the same motion are obtained as limit- ing cases of general solution. Finally, some characteristics of the fluid motion, as well as the influence of pertinent parameters on the behavior of the fluid motion, analyzed by graphs.
