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۔

مؤسسة الإزدواج والأسرة في ضوء الشريعة الاسلامية

Allah Almighty has created everything in pairs. It is a scientific fact that these pairs exist in all things, in vegetable kingdom, even in inorganic matters. There is no doubt that these elements do not exist by themselves. The Holy Quran has mentioned repeatedly this fact in different verses. Marriage in Islam is a divine bond between husband and wife to enjoy the social relationship with each other and is a basic unit of Islamic  family system. This article presents the structure of a Muslim Family in the light Islamic teachings.

Modeling Spatiotemporal Regularity in Deformable Structures

A variety of dynamic objects, such as faces, bodies, and cloth, are represented in computer vision and computer graphics as a collection of moving spatial landmarks. A number of tasks are performed on this type of data such as character animation, motion editing, and nonrigid structure from motion. In theory, many of these tasks are highly under-constrained and the estimation algorithms exploit the natural regularity that exists as a cloud of points moves over time. In this thesis, we present compact and generalizable models of non- rigid objects by exploiting spatial and temporal regularities of time-varying point data. We demonstrate that several theoretically ill-posed tasks can be made well-posed with the help of these models. Our first contribution is to propose and demonstrate the effectiveness of the linear trajectory model for representing time-varying point clouds. Traditionally, a linear shape model has been used to represent time-varying point data; the 3D shape of a nonrigid object is modeled as a linear combination of a small number of basis shapes. In contrast, we represent point trajectories as a linear combination of basis trajectories. We show that the linear trajectory and the linear shape models are dual to each other and have equal representation power. In contrast to the shape basis, however, we demonstrate that the trajectory basis can be predefined by exploiting the inherent smoothness of trajectories. In fact, we show that the Discrete Cosine Transform (DCT) is a good choice for a predefined basis and empirically demonstrate its compactness by showing that it approaches Principal Component Analysis (PCA) for natural motions. This linear trajectory model is applied to the problem of nonrigid structure from motion. Analogous to the formulation under the shape model, the estimation of nonrigid struc- ture from motion under the trajectory model results in an optimization problem based on orthonormality constraints. Prior work asserted that structure recovery through orthonor- mality constraints alone is inherently ambiguous and cannot result in a unique solution. This assertion was accepted as a conventional wisdom and was the justification of several remedial heuristics in literature. In contrast, we prove that orthonormality constraints are, in fact, sufficient to recover the 3D structure in both the linear trajectory and the shape models. Moreover, we show that the primary advantage of the trajectory model over the shape model in nonrigid structure from motion is the possibility of predefining the basis.This results in a significant reduction in unknowns and corresponding stability in estima- tion. We demonstrate significant improvement in reconstruction results over the state of the art. After demonstrating the effectiveness of the linear trajectory model over linear shape model in nonrigid structure from motion, we also show how both the models can be synergisti- cally combined. We present the bilinear spatiotemporal basis as a model to simultaneously exploit spatial and temporal regularities, while maintaining the ability to generalize well to new sequences. The model can be interpreted as representing the data as a linear com- bination of spatiotemporal sequences consisting of shape modes oscillating over time at key frequencies. We apply the model to natural spatiotemporal phenomena, including face, body, and cloth motion data, and demonstrate its effectiveness in terms of compaction, gen- eralization ability, predictive precision, and efficiency against existing models. We demon- strate the application of the model in motion capture clean-up. We present an expectation- maximization algorithm for motion capture labeling, gap-filling, and denoising. The solu- tion provides drastic reduction in the clean-up time in comparison to the current industry standards.
