شیخ مشیر حسین قدوائی
گزشتہ سال کے خاتمہ پر ۲۳؍ دسمبر ۱۹۳۷ء کو شیخ مشیر حسین صاحب قدوائی بیرسٹرایٹ لادتعلقہ دارگدیہ (بارہ بنکی صوبۂ اودھ) نے انسٹھ (۵۹) برس کی عمر میں دل کی پرانی بیماری سے وفات پائی، مرحوم اسلام کے پرجوش سپاہی تھے، عمر بھر فرنگستان کی وادیوں میں اپنے قلم سے مصروف جہاد رہے، ووکنگ مشن کی قلمی کوششوں میں ان کا حصہ نہایت اہم ہے، جنگ عظیم کے زمانہ میں ووکنگ ہی میں مقیم تھے، یورپ کے بڑے بڑے مشاہیر سے ملاقاتیں رکھتے تھے اور دنیائے اسلام کے اکثر اکابر سے ان کی ذاتی واقفیت اور مراسلت تھی، وہ اتحاد اسلامی کی تحریک کے بانیوں اور ملک کے سیاسی آزادی کے حامیوں میں تھے، ۱۹۲۰ء میں فیض آباد خلافت کانفرنس کے صدر کی حیثیت سے انہوں نے جو خطبہ پڑھا تھا وہ ہندوستان میں ترکی اور یورپ کے معاملات کے متعلق پہلا ذریعہ علم تھا، مرحوم اپنی اخیر زندگی تک اسلام کی خدمت میں مصروف رہے، ان کی وفات سے شاید چند ہی روز پہلے ان کی آخری انگریزی تصنیف ’’اسلام اور بولشزم‘‘ چھپ کر نکلی تھی، اﷲ تعالیٰ اس سپاہی کی مجاہدانہ قلمی خدمات کو حسن قبول اور تاثیر بخشے اور اس کو بہشت بریں کی نعمت عطا فرمائے۔
مرحوم سے واقفیت تو ہندوستان ہی میں تھی، مگر میرا ان کا ساتھ ۱۹۲۰ء میں انگلستان میں ہوا، جہاں وہ وفد خلافت کے ساتھ آکر مقیم ہوئے تھے، مرحوم انگلستان کے قیام میں بھی نمازوں کی پابندی کیا کرتے تھے اور وضو اور طہارت کا اہتمام رکھتے تھے، مرحوم ندوہ کے پرانے رکن تھے، ندوہ کی سرکاری امداد کے معاملہ میں ان کی کوششیں بھی شامل تھیں، غالباً ۱۹۰۸ء میں اسی سلسلہ میں جب انگریز انسپکٹر آف اسکولس ندوہ کو دیکھنے کے لئے آیا تو مرحوم اس کے ساتھ تھے، اس زمانہ میں...
Mannerism deals with inner-self and or how to achieve goals in life. It brings harmony in physical and spiritual attributes of a person. As Prophet Muhammad (PBUH) was an excellent example due to His apparent and spiritual moral values that is why The Holy Quran and Hadith direct the society and individual to follow Him. Islam is based on moral values and wishes for a society where people live at individual and community level is having its basis on moral values and spiritualism depicted by the divine teaching. Islamic system preaches good moral values and indicates ways to get saved from ill-mannered behavior. An individual with good moral values reflects good faith and blessings from Allah. Islam promoted a sense of responsibility and fear of the Day of Judgment with Love to Allah in such a way that all the life of an individual was converted to a prayer. This spirit affected all the aspects of individual and society life. This article guides us to understand those moral values.
Strontium hexaferrite nano material with nominal composition SrFe12O19 is prepared by wet chemical methods. The effect of variation in synthesis parameters such as molar ratio of cations (Fe/Sr), volume rate of addition of precipitating agent and the pH of the solution on the phase purity and particle size is studied to optimize them for the synthesis by co- precipitation method. The effect of molar ratio of cations (Fe/Sr) on phase purity is studied by using X-ray diffraction (XRD) patterns. It is observed from indexed XRD patterns that molar ratio of cations does not affect the phase purity of strontium hexaferrites as there is no impurity peak present in any sample and all patterns are almost similar. The effect of volume rate of addition of precipitating agent on phase purity and surface morphology are analyzed by using XRD diffraction patterns and scanning electron micrographs (SEM). The indexed XRD patterns show that the increase in the volume rate of addition of precipitating agent improves the phase purity and SEM micrographs show that the size of the particles also decrease with the increase in the volume rate of addition of precipitating agent. The effect of pH variation on structural and electrical properties of strontium hexaferrite is analyzed by using X-ray diffractometer, scanning electron microscope, temperature dependent dc resistivity measurement system and precision component analyzer. Indexed XRD patterns show that the secondary phases are decreased with the increase in pH of the solution and single phase strontium hexaferrite is obtained for pH=13. The pH of the solution also imparts a significant effect on structural morphology of prepared hexaferrite samples. The SEM micrographs with varying pH samples clearly indicate that most of the particles are of hexagonal shape. It can also be seen that the particle size and their distribution also decrease with the increase in the pH of the solution. The dc resistivity is also increased by increasing pH and this may be due to increase in the grain boundaries. The composition SrFe12-xCrxO19 (X=0.0, 0.2, 0.4, 0.6, 0.8) is prepared in order to increase the coercivity of strontium hexaferrites. Results obtained indicate that Cr doping causes the formation of secondary phases. It is also observed that for X ≤ 0.6, both dielectric constant and coercivity is increased while saturation magnetization is decreased. The increase in coercivity was due to variation in particle size and impurity phases which acted as pinning centers. The decrease in saturation magnetization is because of the replacement of cation (Fe3+) having high magnetic moment (5μB) on octahedral sites with cation (Cr3+) having smaller magnetic moment (3μB). Another composition SrFe12-2xCrxZnxO19 with (X=0.0, 0.2, 0.4, 0.6, 0.8) is prepared with co-precipitation method in order to reduce the dielectric loss tangent. The results show that Cr-Zn doping causes increase in the particle size and decrease in dielectric loss tangent and make the strontium hexaferrite useful for high frequency applications. The hysteresis loops of the Cr-Zn doped samples reveal that both coercivity and saturation magnetization is decreased with increase in doping concentration. The same composition SrFe12-2xCrxZnxO19 with x=0.0, 0.2, 0.4, 0.6, 0.8 is synthesized with WOWS sol- gel method (WOWS stands for Without Water and Surfactants; a new simplified sol-gel method developed in our lab). The structural and dielectric measurements results obtained from the samples prepared with WOWS sol-gel method are better than the results obtained from the same composition prepared with co-precipitation. In some cases, the materials with high loss as well as high dielectric constant may be desired in applications such as electromagnetic (EM) wave absorbing coatings. To achieve these properties, reduction of oxygen from sintered SrFe12O19 is made. This treatment resulted in the increase in the concentration of Fe2+ ions and free iron atoms and hence in the increase in both dielectric constant and dielectric loss and making the material useful for microwave absorption.
