۔مولوی فیروز الدین ڈسکوِی کی ادبی خدمات

مولوی فیروز الدین ڈسکوِی کی ادبی  خدمات

ڈاکٹر نصیر احمد اسد

مولوی فیروز الدین ڈسکوی کی شاعری کے ساتھ ساتھ نثری ادب میں بھی نمایاں خدمات  ہیں۔نثر میں وہ بہترین سوانح نگاروں میں شامل ہیں۔ سوانح نگاری کی صنف باقی اصنافِ نثر کے مقابلے میں اپنے ماحول اور اس کے رحجانات کی عکاسی زیادہ بہتر انداز میں کرتی ہے۔ اُردو میں سوانح نگاری کا آغاز عہد سر سید سے ہوتا ہے۔ حالی کی ’’حیاتِ جاوید ‘‘ ،’’یادگارِ غالب‘‘ شبلی کی ’’سیرت النبیؐ ‘‘ اور ’’سیرت النعمان‘‘ میں سوانح نگاری کے قائم کردہ معیار کی پیروی ایک عرصے تک کی جاتی رہی۔ سرسید کا دور مذہبی مناظر ے اور بحث و مباحثے کا دور ہے لہٰذا اس دور کی سوانح عمریاں اپنے عہدکی عکاس ہیں۔اس دور کے مشہور سوانح نگاروں میں : مرزا حیرت دہلوی، احمد حسن خان، عبدالحلیم شرر، منشی محمد الدین فوق، مولوی احمد دین ،احمد حسین الہٰ آباد ی ، مولوی ذکاء اللہ ، سراجدین احمد ،نذیر احمد ،قاضی سلیمان ،عبدالرزاق کانپوری اور مولوی فیروز الدین ڈسکوی اہم ہیں۔

فضائل اسلام فی ذکر خیر الانام المعروف سیرت النبیؐ یا تاریخ نبویؐ مولوی فیروز الدین ڈسکوی کی پہلی باقاعدہ نثری تالیف ہے۔ اس کتاب کا پہلا ایڈیشن مفید عام پریس لاہور سے ۱۸۸۶ء میں شائع ہوا۔ اور’’ نماز اور اس کی حقیقت‘‘ مولوی صاحب موصوف کی دوسری نثری تالیف ہے ۔یہ کتاب منشی فیض علی نے پنجاب پریس سیالکوٹ سے ۱۸۹۰ ء میں شائع کی۔ ’’تفسیر فیروزی پارہ اول‘‘ مولوی صاحب کی تیسری تصنیف ہے۔ یہ کتاب ۱۸۹۰ء میں سیالکوٹ مفید عام پریس سے شائع ہوئی۔ ’’تکذیب و ید‘‘ مولوی صاحب کی چوتھی تصنیف ۱۸۹۰ء میں پنجاب پریس سیالکوٹ سے شائع ہوئی۔ ’’تصدیق الا لہام‘‘ مولوی صاحب موصوف کی مناظراقی تصنیف ہے۔ جو ۱۸۹۰ء میں...

الأخبار الموضوعة في سنن ابن ماجه: دراسة نقدية

The scholars of Hadith gave special attention to the fabricated hadith and they explained it to others and warned about its danger. They all agreed upon it that transmission of fabricated report is unlawful only one way is lawful if the status of this report is narrated with its transmission. Some great scholars of hadith like Mizzi, Zahabi and Ibn Hajr have pointed out that in the sunan of Ibn Maja there are some fabricated and false ahadith. I took interest in study of these fabricated ahadith and I separated them and studied these ahadith according to the Principles of research of this filed. You will find during the study of this paper the importance of Sunan among the six books. You will study comments of scholars about this book. After complete study of this paper, we can conclude following points: 1. There are forty-four fabricated ahadith in Sunan of Ibn Maja. 2. These ahadith are found in five books except one, hadith is narrated by only Ibn Maja. 3. Ibn Maja declared about only one hadith that it is baseless. 4. Ibn Juzi mentioned only seven ahadith in his book fabricated ahadith. 5. Imam Bausairi showed indefference in commenting and declaring these ahadith as fabricated in his book Misbah-uz- zujazah. Although there are clear signs of fabrication in these ahadith.

Pathogenesis of Aflatoxin B1 in Quails under Experimental Conditions and Detoxification by Biological and Chemical Means

Secondary metabolites of certain fungi produce toxins under favorable conditions especially while growing on different food grains. Mycotoxins are among major threats to growing poultry industry and human beings. Aflatoxins are closely related, biologically active fungal metabolites and commonly produced by Aspergillus species. A research was carried out to evaluate the ability of Aspergillus flavus for Aflatoxin B1 production using rice, wheat and maize as substrates. Lethal effects on growth performance parameters, hematological and histopathological of graded doses of aflatoxin B1 in quails under experimental conditions were observed. Effect of Aflatoxin B1 on humoral immune response to Newcastle Disease virus vaccine in quails were determined. Biological detoxification of Aflatoxin B1 by Saccharomyces servisiae was evaluated in quails. Comparative evaluations of different commercially available toxin binders were checked. All these experiments were carried out till the six weeks (42 days). Aspergillus flavus was identified on the basis of macroscopic and microscopic characteristics. Rice, wheat and maize grains was used as substrate to check the level of Aflatoxin B1 produced by inoculating an aqueous suspension of 106 spores/ml. Aflatoxin B1 checked by Thin Layer Chromatography (TLC) and quantified by High Performance Liquid Chromatography (HPLC). Quails were reared under standard management conditions in five groups (A, B, C, D and E) having sixty each. Each group was further divided in two independent units. Diets offered to groups were control (without toxins), 0.25, 0.50, 1 and 2 mg Aflatoxin B1/kg feed. One unit of each group was vaccinated with Newcastle Disease Virus (NDV) vaccine while other was not and studied the lethal effects on growth performance, blood parameters, immune response and histopathology of vital organs. At the end of the experiment, it was found that the deleterious effects of Aflatoxin B1 were dose and duration dependent. As the level of the toxin was increased, the lethal effects were prominent. The growth performance parameters including gain in body weight, feed intake and feed conversion ratio was adversely affected at high doses. The body weight gain was significantly reduced in Aflatoxin B1 treated groups as compared to control group. Similarly feed intake and feed conversion ratio were significantly different from the control group. The hematological studies exhibited that aflatoxin B1 significantly reduced the hemoglobin, packed cell volume and total leukocyte count whereas the erythrocyte sedimentation rate was significantly increased as compared to control group. The immune response against NDV vaccine was adversely effected in Aflatoxin B1 treated groups and values of Antibody titer in AFB1 were significantly low as compared to group A( control) In the second experiment, Saccharomyces cervisae (SC) dried powder was mixed in basal quail diet having 0.5mg Aflatoxin B1 for all experimental groups and control was without toxins. SC was added at levels of 0.5 gm, 1.0 gm and 2.0 gm /kg of feed. It was recorded that Saccharomyces cervisae (yeast) have the potential to remove the deleterious effects of Aflatoxin B1. Yeast effectively detoxified the Aflatoxin B1. The results recorded of growth performance and other parameters were non-significantly different from the control group. Chemical detoxification of Aflatoxin B1 was evaluated in quails using commercially available toxin binders. Toxin binders used were activated charcoal, kaoline, Myco AD and selenium plus vitamin E and mixed in basal quail diet having 0.5mg Aflatoxin B1 for all experimental groups and control was without toxins. The Myco AD and selenium plus vitamin E showed the highest detoxification potential as compared to other chemical toxin binders. Groups E and F showed the results of growth performance, hematological, immune response and histopathological were non-significantly different from the control group (A). Kaolin was moderately detoxifying the toxin. Presence of aflatoxin B1 in soft tissues was checked by TLC and quantified using HPLC. The liver exhibited the residues of Aflatoxin B1 at high doses of toxin. Group D and E rearing on feeds having 1mg AFB1 /Kg feed and 2mg AFB1 /Kg feed of toxin showed the residues of AFB1 in liver and kidney. Statistical means for growth performance parameters, hematological, immune response and histopathological scores in each subunit of quails were analyzed by applying one way ANOVA and Duncans‟s Multiple Range (DMR) test at 95% probability. Aflatoxin B1 is lethal and lowers the performance of birds. The lethal effects can be detoxified by biological and chemical means to lower the economic losses to poultry industry. It can be concluded that biological detoxification is preferably better as compared to chemical detoxification.
