a-amylase is an industrially important enzyme that catalyses the hydrolysis of starch to yield products like glucose and maltose. Optimization of a-amylase production by isolate Bacillus amyloliquefaciens S8TS was done using technique of solid state fermentation (SSF). Different types of agro-industrial substrates (wheat straw, rice husk, wheat porridge, wheat bran) were used for the production of a-amylase but wheat bran gave highest a-amylase activity (3.50 ?0.088 U/mg) when moisten with 10 ml diluent (D-3) at pH 7.0, temperature 37oC with 10% vegetative inoculum after 72 h of incubation.

مولانا ابوسلمہ شفیع احمد

آہ! مولانا ابوسلمہؒ
(پروفیسر مسعود حسن)
۲۲؍ دسمبر کی دوپہر کو کلکتہ کے مسلمان ایک بڑے المناک سانحہ سے دوچار ہوئے، یہ سانحہ حضرت مولانا ابوسلمہ شفیع احمد صاحبؒ کی رحلت ہے، جو ۵-۴ ماہ کی طویل اور صبر آزما علالت کے بعد ۷۳ سال کی عمر میں اپنے مالک حقیقی سے جاملے۔ اناﷲ وانا الیہ راجعون، دوسرے دن صبح ۳۰:۱۲ بجے ان کے ہزاروں عقیدت مندوں اور جان نثاروں نے ان کے جسدخاکی کو پارک سرکس سے متصل ایک قبرستان میں جس کا نام ہم ’گورغریباں‘ ہے، یہ کہہ کر سپردخاک کیا کہ:
اے تیرہ خاک خاطرِ مہماں نگاہ دار
کیں نورچشم ماست کہ دربر گرفتہ ای
نور اﷲ مرقدہٗ و برد اﷲ مضجعہ
مولانا مرحوم کے نام اور مقام سے مجھے بہت پہلے سے واقفیت تھی، البتہ باقاعدہ نیاز اور تقریب ۱۹۵۹؁ء میں حاصل ہوا، جب مجھے مدرسۂ عالیہ کلکتہ کی پرنسپلی تفویض ہوئی اور میں مدرسہ پہنچا، مولانا مدرسہ کے ممتاز ترین اساتذہ میں تھے، تفسیر اور حدیث ان کے خاص موضوع تھے اور ان دونوں فنون کی بیشتر متداول کتابوں پر ان کی گہری نظر تھی، وہ مدرسہ کی اونچی جماعتوں میں درس دیتے تھے اور بڑی عزت و احترام کی نظر سے دیکھے جاتے تھے۔ میں مدرسہ میں کم و بیش ۵ سال رہا۔ اس پوری مدت میں میرے ان کے تعلقات مخلصانہ رہے اور جب میں وہاں سے رخصت ہوا تو اس کے بعد بھی ان کا اخلاص برابر جاری رہا۔ وہ اکثر میرے غریب خانہ پر تشریف لاتے، گھنٹوں بیٹھتے تھے۔ راقم الحروف بھی ان کی خدمت میں حاضر ہوتا تھا، ان ملاقاتوں میں اکثر علمی گفتگو ہوا کرتی تھی، کبھی کبھی حالات حاضرہ پر بھی تبصرہ ہوا کرتے تھے، مولانا ان مجلسوں میں علم و حکمت کے موتی بکھیر دیتے تھے۔

حضرت محمدﷺ کے معجزۂ معراج اور اسراء کے متعلق سرسید احمد خان کا تصور

Amongst other miracles of the Prophet Muhammad (PBUH), ISRAA and MAIRAAJ are one of the well-known miracles that have been discussed a lot in Sirat-ul-Nabi. This article, therefore, has brought under discussion the occur-rence of this miracle in the light of Qura’n and Ahadith in details.  Furthermore, it has also been discussed whether the occurrence of this miracle was physical or spiritual in its nature.  The concept of Sir Syed Ahmed Khan regarding this miracle has also been discussed; where he support his arguments with reference to some Ahadith, that the entire situation concerning the miracles was merely a dream and this miracle did not take place in physical form. According to him, this is against the law of nature. In this article the explicit concepts of Sir Syed Ahmed Khan have been rejected with the arguments given by the Majority of the Scholars and Muslim thinkers.
