پروفیسر آل احمد سُرور
۹؍ فروری ۲۰۰۲ء کو اردو کے بزرگ استاذ، اردو تحریک کے معمر قائد، اردو کے سب سے بڑے ادیب و نقاد، اچھے شاعر، نامور اہل قلم، غالب و اقبال کے پایہ شناس اور علی گڑھ اور سر سید احمد خاں کے عاشق و شیدائی پروفیسر آل احمد سرور رحلت فرماگئے، اناﷲ و انا الیہ راجعون اور پوری اردو دنیا کو مغموم، سوگوار اور اداس چھوڑ گئے ع مجنوں جو مر گیا ہے تو جنگل اداس ہے۔
اردو کی اس کسمپرسی کے دور میں اس کے ایک نہایت ممتاز عالم اور دانشور کا اُٹھ جانا حادثہ جاں کاہ اور اردو کا بڑا زیاں اور خسارہ ہے۔
موت و حیات کا سلسلہ ازل سے جاری ہے اور ابد تک جاری رہے گا لیکن برسوں کی گردش فلک کے بعد سرور صاحب جیسا مایۂ ناز انسان پردہ خاک سے نکلتا ہے، ان ہی کا شعر ہے
ستارے کتنے یہاں ڈوبتے ابھرتے ہیں
کبھی کبھی ہی نکلتا ہے آفتاب کوئی
ان کا خلا کیسے پُر ہوگا اور اردو زبان، ادب اور تنقید کے نقصان کی تلافی کیسے ہوگی،
اک دھوپ تھی کہ ساتھ گئی آفتاب کے
پروفیسر آل احمد سرور ۱۹۱۱ء میں بدایوں میں پیدا ہوئے، ابتدائی اور ثانوی تعلیم پیلی بھیت اور غازی پور میں حاصل کی، آگرہ سے بی۔ایس۔سی کیا، ۱۹۳۲ء میں علی گڑھ مسلم یونیورسٹی میں داخلہ لیا اور ۱۹۳۴ء میں انگریزی میں ایم۔اے کر کے اسی کے استاد ہوگئے۔ اردو ان کی محبوب مادری زبان تھی، ۱۹۳۶ء میں اس میں ایم۔اے کر کے انگریزی سے اردو شعبہ میں منتقل ہوگئے اور اسی زبان سے پیمانِ وفا باندھ لیا، چاہتے تو کوئی اعلا سرکاری عہدہ مل جاتا لیکن انہیں اپنی زبان اور اپنی تہذیب زیادہ عزیز تھی اس لیے سائنس اور انگریزی جیسے سکہ رائج الوقت کو بھنانے کے بجائے...
Arabian Peninsula was famous for its language expertise and linguistic expressions at the time of Prophet Muhammad (ﷺ). The poets and language experts would spend most of their lives to attain excellence in Arabic language and literature. It was during such time that a man named Muhammad (ﷺ) emerged, whose linguistic expression was remarkable, accurate and amazing. He was also quite familiar with the dialects and accents of every tribe of Arabia. It was the surprising effect of this linguistic excellence that people tagged him with different titles such as Poet, Sorcerer, Kāhin (soothsayer), Majnūn (One possessed by Jinn), and insane man with insane message. Allah Almighty revealed Qur’ānic verses not only to answer such allegations but also entrusted him to present commentary of the Holy Qur’ān to the people who would called him illiterate. This article will try to find out the Qur’ānic commentary on the linguistic expressions of Prophet Muhammad (ﷺ) as a miracle of revelation. The method of research is descriptive analytical and historical. The discussion of verses of Qur’ān and the explanations of the experts of Qur’ān through the comments of orientalists have been included to support the arguments. First Part of the paper discusses status of Prophet Muhammad (ﷺ) as an illiterate man with his remarkable linguistic expressions of Qur’ān due to which he was awarded different titles such as poet, sorcerer and insane. The second part explains the Qur’ānic response to accusations on Prophet (ﷺ) raised by the opponents. In the third part, some intellectual arguments of Qur’ān and opinions of orientalist have been discussed to support the Qur’ānic responses in favor of linguistic expressions of an “Ummi” Prophet Muhammad (ﷺ) which is followed by findings and conclusion of the whole discussion.
Inspired from the natural photosynthesis in which solar radiation is being effectively utilized in photoconversion of simple compounds (H2O and CO2) into carbohydrates and oxygen, scientists are dragged toward artificial photosynthesis for obtaining important chemicals from cheap and sustainable sources. The efficient conversion of solar energy into clean form chemical energy is the concept that is considered to be effective solution of world’s growing issues i.e. increasing demand of the fossil fuels and global warming. Hydrogen is considered as the fuel of the future because it has more energy capacity than fossil fuel, yielding zero carbon emission and has competency to replace the fossil fuels being used in different sectors. Photoelectrochemical (PEC) splitting of water is considered as one of the most promising technology by which solar energy could be efficiently utilized in hydrogen generation from its cheap and abundantly available source i.e. water. In this work, we focussed on the use of α-hematite/ferrites composite thin films as electrode material for photoelectrochemical water oxidation. Based on the band gap and their band alignment knowledge, three different series of composite thin films i.e. (1) CuFe2O4/α-Fe2O3, (2) ZnFe2O4/α-Fe2O3 and (3) NiFe2O4/ α-Fe2O3 were deposited on planar and 3-dimentional (3-D) nanostructured substrates. The fabricated devices were then structurally and morphologically characterized by various techniques and evaluated for photoelectrochemical water oxidation applications. It has confirmed that the ratio between the components of the composite thin films is crucial, so the highest activity results were obtained by the thin films devices having equal molar ratio (1:1) between α-hematite and ferrites in all the three classes. Among CuFe2O4/α-Fe2O3 composite thin films series, the CF-1, having 1:1 molar ratio between CuFe2O4 and α-Fe2O3 showed the highest activity. This composite when deposited on planar FTO coated substrate showed the highest photocurrent density of 1.24 mA/cm2 at the applied voltage of 1.23 VRHE and retained the photoconversion efficiency of 0.14%. The same material when deposited on 3-D nanostructured substrate, an increase in the photocurrent density upto 2.2 mA/cm2 at the same applied voltage was recorded. Among ZnFe2O4/α-Fe2O3 composite thin films, we found that nanostructured device (ZF1-NSP) having molar ratio of 1:1 between their components retained the highest photocurrent density of 2.19 mA/cm2 and showed the photoconversion efficiency of 0.22%. This photocurrent density is 3.4 and 2.73 times higher than photocurrent density values of pure hematite on planar FTO and the highest reported value of ZnFe2O4/α-Fe2O3 composite, respectively. Among NiFe2O4/α-Fe2O3 composite thin films, the highest photocurrent density of 2.1 mA/cm2 at 1.23 VRHE was obtained for the composite device having 1:1 molar ratio of NiFe2O4/α-Fe2O3 iii deposited on 3-D nanostructured substrate (NF1-NSP), which was 3.3 times more photocurrent density than pure hematite. It has been verified by electrochemical impedance spectroscopy (EIS) that α-hematite/ferrite composite thin films have greater conductivities of charge carriers than α-hematite and the highest values of charge conductivities were obtained for the composites consisting of equal molar ratio between α-hematite and ferrite. Based on photoluminescence studies, the photogenerated charge recombination has also been decreased by increasing ferrite component in α-hematite/ferrite composite. So, the better activities of α-hematite/ferrite composite in PEC water oxidation is provided by greater electrical conductivity and reduced charged recombination as compared to pure α-hematite. The performance of 3-D nanostructured devices in photoelectrochemical water oxidation were much greater than planar devices with the similar composite thin films. The three dimensional architecture of the electrode offers large surface area for the redox reaction and larger capability to harvest visible light for enhancing the performance of 3-D nanostructured electrode as compared to planar electrode.
