قاضی زین العابدین میرٹھی

قاضی زین العابدین
میرٹھ کے عالمِ دین قاضی زین العابدین ایک بڑے اسلامی مصنف بھی تھے۔ادارہ ندوۃ المصنفین سے ان کی عظیم وضخیم کتاب تاریخ مِلّت تین حصّوں میں شائع ہوچکی ہے،پہلا حصّہ نبیؐ عربی، دوسرا حصّہ خلافت راشدہ اور تیسرا حصّہ خلافت بنوامّیہ پرتھاجوعلمی حلقوں میں مستند وپسندیدہ ہیں۔قبلہ اباجان حضرت مفتی عتیق الرحمان عثمانیؒ سے ان کو خصوصی لگاؤ وانس تھا۔ ان کانام جب بھی لیتے تعظیم و تکریم سے ہی لیتے۔
دارالعلوم دیوبند کی مجلس شوریٰ کے ممبر تھے۔جمعیۃ العلماء ہندسے وابستہ تھے۔حضرت مولیٰنا اسعد مدنی صاحب،حضرت مفتی عتیق الرحمان عثمانیؒ کی ہمیشہ ہی عزت و تکریم کرتے تھے۔جب جمعیۃ العلماء ہندکے سلسلے میں مولیٰنا اسعد مدنی سے حضرت مفتی صاحب کے بعض معاملات میں اختلافات ہوئے تب بھی یہ دونوں بزرگ ہمیشہ ہی حضرت مولیٰنا مفتی عتیق الرحمان عثمانیؒ کاادب ولحاظ کرتے تھے اور عزت و تکریم میں ہمیشہ ہی بازی لے جانے کی کوشش کرتے۔
مولیٰنا قاضی زین العابدین صاحبؒ قبلہ ابّاجان مفکّرِ ملّت حضرت مفتی عتیق الرحمان عثمانیؒ کے شیدائی تھے اور میرے بھائی نجیب الرحمان عثمانی کے سسرالی رشتے کے بزرگ بھی تھے۔ حضرت مفتی شوکت علی فہمیؔ (اﷲ تعالیٰ ان کی عمر دراز اورصحت و تندرستی عطا فرمائے)کے عزیز خاص تھے۔ان کے انتقال سے علمی ودینی حلقوں میں صف ماتم بچھ گئی ہے۔ ابھی حضرت مولیٰنا قاضی سجاد حسین صاحب ،حضرت مولانا محمد تقی امینی اور مولیٰنا ابواللیث کاصدمہ ہی ہرا تھا، ان کی وفات سے ہمارے آنسو خشک نہ ہوئے تھے کہ برہان کوان کی وفات کاعظیم صدمہ ہوگیا۔
ادارہ ندوۃ المصنفین دہلی حضرت مولیٰنا منّت اﷲ رحمانی (امیر شریعت بہار) اور حضرت مولیٰنا قاضی زین العابدین صاحبؒ کے انتقال پُرملال پرخود اپنے سے، ملّت اسلامیہ سے اور تمام لواحقین سے اظہار تعزیت کرتے ہوئے دعاگو ہے کہ اﷲ تعالیٰ انھیں کروٹ کروٹ جنّت نصیب فرمائے۔آمین۔

آخرت سے متعلق ”ترجمان القرآن“ کے کلامی مباحث کا تجزیاتی مطالعہ

In this universe, if we look at the arrival of a human being, it will open up to us the secret that man did not come in this world suddenly, but he had gone through several worlds before stepping into this universe. The First World is called spiritual world where his soul was present and the argument is that when the soul enters the body of the baby and he starts to move in the womb of the mother, so the question now arises where was that soul before it entered the baby’s body? And where did that soul come from? Where it was and wherever it came from, the name of that universe is Spiritual world. After the spiritual world, there is a second world in the womb of the mother. In this world a man must live for at least nine months. Stop for a minute to see this amazing system of power that a baby remains alive in a moving grave for at least nine months. The object is to say that if a human being has to go through two worlds before coming into the universe, so if a fourth world is accepted after this world, what is the rational prohibition behind it? The life in the fourth world is called the life of Hereafter. If there is any disagreement with this name then let’s another name, but a fourth world still have to believe, because when the soul comes out of body after death, the same question will arise here that where did the soul go? In this article, it is examined that how author of “Tarjuman al-Qur’an” Abul Kalam Azad has proved the reality of life of Hereafter and what kind of arguments have given as an evidence in this tafsir?

Electronic and Optoelectronic Studies of Organic Semiconductors

Organic semiconductors have made inroad into many area of devices which was formally dominated by inorganic semiconductors because of their wide variety of electronic and optoelectronic properties. They being low cost, light weight and low temperature processing materials provide opportunities to fabricate the variety of devices, such as, solar cells, field effect transistors, lasers, light emitting diodes, sensors, photo detectors, smart windows, large area displays, e-paper, etc. The material manipulation, low cost fabrication techniques and the emerging ideas are bringing about much improved performances in the organic electronic devices. Most of the earlier studies have been reported on the p-type organic semiconductors and little is known about n-types. In the development of future organic electronic industry, all organic complementary circuits are not possible without the availability of both p- and n-type organic semiconductors and data is required on the junction properties and mobility studies of these materials. Plenty of data is available on the junction diodes of p-type organic semiconductors but little is known on the n-type organic semiconductors based junction devices and mobility investigations. In this dissertation, the n-type organic semiconducting materials formyl- TIPPCu(II), N,N ́-di-n-heptyl-2,3:6,7-anthracenetetracarboxydiimide (ADCI7) and N,N ́- di-n-octyl 2,3,6,7 anthracenetetracarboxydiimide (ADCI8) have been investigated as active organic materials for their potential application in organic electronic devices. Using organic semiconductor formyl-TIPPCu(II), junction diode, temperature, light and humidity sensors have been fabricated, while ADCI7 and ADCI8 have been used for the fabrication of n-channel organic thin film transistors. To investigate junction properties of formyl-TIPPCu(II) organic semiconductor, fabrication of Ag/formyl-TIPPCu(II)/p-Si heterojunction diode was undertaken and it was made successfully. Its temperature dependent electrical properties are reported. The values of series resistance, ideality factor, zero bias barrier height are observed strongly dependent on temperature. The series resistance and ideality factor decease while the zero bias barrier height increases with the rise in temperature. viiThe surface type Ag/formyl-TIPPCu(II)/Ag humidity sensors has been fabricated to study the effects of changing relative humidity on the electrical parameters and their frequency dependant responses. The values of capacitance and resistance of the sensors were measured at different humidity levels at frequencies of 1 kHz, 10 kHz and 100 kHz. An increase in capacitance and decrease in resistance were observed during the rise of relative humidity from 45 to 95% RH. The hysteresis response of these humidity sensors was also studied at the frequency of 1 kHz. Effects of temperature and light are studied on the capacitance and resistance of the Au/formyl-TIPPCu(II)/Au device. The relative capacitance of the fabricated sensor increased by 4.3 times by rising temperature from 27 to 187 0 C, while under illumination up to 25000 lx, the capacitance of the Au/formyl-TIPPCu(II)/Au photo capacitive sensor increased by 13.2 times as compared to dark conditions. ADCI7 and ADCI8 were used to fabricate n-channel organic thin film transistors (OTFTs) on oxidized silicon wafers. To get the high performance of the devices and to avoid the trapping of charge carriers, the dielectric surface were modified by developing the buffer layer of PMMA or by self assembly monolayer (SAM) of HMDS. The OTFTs exhibited high charge mobility of the order of 10 -2 cm 2 V -1 S-1 (ADCI7) and 10 -3 cm 2 V -1 S - 1 (ADCI8) with the on/off ratio of the order of 10 4 showing the appreciable enhancement in the field effect properties of these materials as compared to the previously reported researches for the same family of materials. ADCI7 is introduced as new compound for high mobility n-channel OTFTs.
