مولانا عاشق حسین سیماب اکبر آبادی
افسوس ہے پچھلے دودن کے ہی آگے پیچھے سے اردو کی بساط شعروادب کے دوپرانے اورنامور مہرے اٹھ گئے۔مولانا عاشق حسین سیماب اکبر آبادی اور مولانا احسان اﷲ خاں تاجورؔ نجیب آبادی آج کل کے عام شاعروں کی طرح شاعر یاادیب ہی نہیں تھے بلکہ صاحب فن استاذ،علم عروض ومعانی وبیان اور لغت و قواعد لسان کے بڑے مبصر اورناقد بھی تھے۔مولانا سیماب۱۸۸۰ء میں آگرہ میں پیداہوئے اورجنوری۱۹۵۱ء میں کراچی میں انتقال کرگئے شاعری اٹھارہ انیس برس کی عمر سے ہی شروع کردی تھی اس طرح گویا مرحوم نے پوری ایک نصف صدی اردو زبان وادب کی خدمت میں بسر کی۔اس مدت میں سینکڑوں چھوٹی بڑی کتابیں اوربے شمار مقالات،نظمیں وغیرہ ان کے قلم سے نکلیں۔ان کے شاگردوں کاحلقہ بھی نہایت وسیع تھا جو خط وکتابت کے ذریعہ ان کی فنی بصیرت ومہارت سے استفادہ کرتارہتاتھا۔ابتدا میں اگرچہ مرزاداغ سے مشورہ سخن کرتے تھے مگر جلد ہی ان کااپنا ایک مخصوص رنگ قائم ہوگیا۔کثرت مطالعہ وفکر عمیق نے ان میں شعروادب سے متعلق ایک مجتہدانہ شان پیداکردی تھی۔وہ کسی کے مقلد نہیں تھے بلکہ ہرچیز اورہرشعری وادبی مسئلہ کے متعلق اپنی ایک جچی تلی سنجیدہ اورمتین رائے رکھتے تھے اورعلیٰ وجہ البصیرت رکھتے تھے۔انھوں نے اپنی زندگی میں بڑے بڑے طوفانی اورانقلابی دوردیکھے جس نے ادب وشعر کی پرانی قدروں کومتزلزل کرکے رکھ دیا اورصورت ومعنی دونوں کے لحاظ سے شاعری کی دنیا میں ہنگامہ برپاکردیا، لیکن مرحوم ایک چٹان بنے اپنے مقام پرکھڑے رہے یہاں تک کہ انقلاب فکروسخن کی موجیں ان سے ٹکرائیں اوربالآخر راستہ کاٹ کر ان سے دامن بچاکر نکل گئیں۔یہ سب کچھ اس لیے ہوسکا کہ مرحوم طرزقدیم کے حامل ہونے کے ساتھ وقت کے جدید تقاضوں سے بھی بے خبر نہ تھے اورقدیم وجدید میں ہم آہنگی پیداکرلینے کاان میں بڑااچھا سلیقہ تھا۔آخر عمر...
The account of the deeds and sayings of the prophet (ﷺ) has been carefully preserved since the dawn of Islam. This is what actually led Ernest Renan to believe that “[Islam] was born in the full light of history”, and that the life of Muḥammad (ﷺ) can be known as explicitly as that of any sixteenth century reformer. Notwithstanding, some contemporary writers doubt the historicity of Muḥammad (ﷺ) ; Robert Spencer is one of them. He is an American author. He is quite famous for his criticism of Islam and the prophet of Islam. He has published twelve books so far. He is a member of Melkite Greek Catholic Church. He contends that Muḥammad’s (ﷺ) historical value is in no way greater and more reliable than mythological figures or characters such as Robin Hood and Macbeth. He maintains that the very idea of subjecting the traditionally accepted account of the life of Muḥammad (ﷺ) and the origins of Islam will be regarded by many Muslims as an affront. To substantiate his argument, he rigorously criticizes the historical value of ḥadīth. He argues that aḥādīth were fabricated and compiled in the third century. He maintains that aḥādīth were concocted much later to be used as weapons in political strife and religious controversies. This paper is an academic attempt to prove that aḥādīth were painstakingly preserved and for that purpose various techniques were employed. Besides, it also sheds light on the reasons for the fabrication of aḥādīth and the ways and means utilized for sifting the genuine aḥādīth from forgeries. Findings of this article suggest that the minute details of the life of Muḥammad (ﷺ) have been scrupulously preserved; hence aḥādīth can be used as a reliable source of Sīrah.
Since the deployment of 1G cellular networks, cellular operators are constantly striving towards achieving higher data rates. Next generation networks are expected to meet the demands of subscribers for high data rates. To meet these challenging requests of higher data rates, the telecom research community is focusing its attention towards hexa dimensional resource management techniques in next generation cellular networks. These techniques include use of heterogeneous networks (hetnets), power allocation, channel allocation, broad band and efficient spectrum utilization, noise control methods and interference management. In next generation networks, a major portion of system throughput enhancements is expected to come from device to device (D2D) communication which is viewed as part of hetnets. In this thesis, D2D communication is considered the main enabling feature of hetnets to enhance throughput and its intelligent resource management is imperative. The scope of this work is further broadened by integration of cognitive radio network (CRN) concepts into the D2D resource management. To further boost data rates, D2D concept is extended by incorporation of communication among devices to devices (Ds2Ds) and their intelligent resource management. Resource management is a domain wherein resources are intelligently allocated to various users. Resource management aspects considered in this thesis include admission control, mode selection and power allocation. This work considers D2D joint resource allocation to maximize the overall throughput of cellular networks having D2D capabilities while observing the sanctity of constraints of power, quality of service (QoS) and interference. This problem is NP-complete and is classified as mixed integer non-linear optimization problem. Computational complexity of the exhaustive search algorithm (ESA) increases exponentially with the number of users. This makes it very difficult to find optimal solution for such kind of problems. In this work, convergent solutions for solving the joint resource allocation problem in D2D communication has been presented. By exploiting the special structure of the problem, outer approximation algorithm (OAA) and mesh adaptive direct search (MADS) algorithms have been used to obtain epsilon-optimal solution. Using joint utility function, different scenarios of simulation results confirm effectiveness of MADS viz-a-viz OAA. Performance of MADS was found to be equal to that of ESA. Cognitive assisted D2D network is an emerging domain which utilizes television (TV) white space spectrum. Joint resource allocation of CRN assisted D2D networks along with constraints of transmit power, QoS and interference (related to TV users) is considered in this thesis. The problem is mathematically modelled with a utility function having two terms related to maximization of admitted users and maximization of overall system throughput. MADS algorithm is adopted for solution of NP-complete problems. Simulation results compare different scenarios using ESA and MADS algorithm. Results of simulation testify to the fact that MADS provides solution close to optimal with reasonable complexity. In Ds2Ds resource management problem, the objective is to maximize energy efficiency of Ds2Ds communication, subject to compliance of constraints related to radio resources, quality of service (QoS) and interference. Performance of Ds2Ds is bench marked with multi-homing technique and devices to device (Ds2D) communication. The objective of maximization of energy efficiency reinforces the much sought-after green communication.
