ڈاکٹر سید عبداللطیف
ہماری بزم علمی کی پرانی یادگاریں روز بروز اٹھتی جاتی ہیں اور ہر مہینہ کسی نہ کسی کا ماتم کرنا پڑتا ہے، گذشتہ مہینہ دو نامور اہل علم نے وفات پائی، ہندوستان میں ڈاکٹر سید عبداللطیف نے اور پاکستان میں غلام رسول مہر نے، ڈاکٹر صاحب اس دور کے نامور فاضل اور انگریزی کے مشہور اہل قلم تھے، ان کی پوری زندگی علمی و تعلیمی مشاغل میں گذری، وہ جامعہ عثمانیہ میں انگریزی یا فلسفہ کے پروفیسر تھے، اس سے ریٹائر ہونے کے بعد ان کا سارا وقت تالیف و تصنیف میں گزرتا تھا، وہ راسخ العقیدہ مسلمان تھے، ان کے دل میں مذہب و ملت کا درد تھا، اسلامیات پر بھی ان کی نظر وسیع تھی، کلام مجید سے خاص شغف تھا، ان کی بیشتر تصانیف اور مضامین کلام مجید اور اسلامی تعلیمات اور تہذیت و ثقافت کے کسی نہ کسی پہلو پر ہیں، انھوں نے کلام مجید اور مولانا ابوالکلام آزاد کے ترجمان القرآن کا انگریزی ترجمہ کیا، یہ دونوں شائع ہوچکے ہیں، انگریزی تصانیف میں The Mind Al-Quran Builds زیادہ مشہور ہے، اس کا اردو ترجمہ چھپ چکا ہے، ایک کتاب اردو میں ’’اساس تہذیب‘‘ کے نام سے لکھی اس میں کلام مجید اور احدیث نبوی سے عالمگیر انسانی تہذیب کے عناصر دکھائے گئے ہیں، اردو شعر و ادب سے بھی ذوق تھا، انھوں نے غالب پر انگریزی میں ایک کتاب لکھی، اس میں ان کی زندگی کے وہ پہلو بھی دکھائے گئے ہیں، جن سے ان کے سوانح نگار اغماض برتتے ہیں، ان مستقل تصانیف کے علاوہ انھوں نے مذہب اسلام اور اسلامی تہذیب و ثقافت پر بکثرت مضامین لکھے، ان کا آخری کارنامہ یہ ہے کہ اپنی وفات سے پہلے انھوں نے قرآنی ٹرسٹ کے نام سے ایک ٹرسٹ قائم کیا اور اس کو اپنی تمام تصانیف کا حق...
Maulānā Muḥammad Ismāʿīl al-Ūdwī al-Shikārpurī (1897-1970) was one of the very prominent scholarly personalities of Pakistan. His life and works are studied and analyzed in detail elsewhere. (See. IRJAH, Faculty of Arts, University of Sindh, Jamshoro, Vol. 42, 2014 and Ma’arif Research Journal, Islamic Research Academy, Karachi, issue. 13, 2017). This paper mainly deals with al-Ūdwī’s theory of iʿjāz al-Qurʾān. With regard to the theory of iʿjāz al-Qurʾān, classical scholars including al-Rummani, al-Khaṭṭābī, al-Baqillani, al-Rāzī significantly emphasize the linguistic nature of iʿjāz as an argument to support the doctrine of iʿjāz al-Qurʾān. Al-Ūdwī on the other hand, after accepting the linguistic iʿjāz of the Qurʾān, proceeds to go further than his predecessors in supporting the doctrine of iʿjāz al-Qurʾān by emphasizing and situating iʿjāz in the content of the Qurʾān. Therefore, his book Nūr al-Īqān bi iʿjāz al-Qurʾān seems to be considerably different in its arguments from his predecessors’ theory. There is no exaggeration to say that al-Ūdwī has distinctly added several new arguments in his book, which, according to him, provide the certainty in the doctrine of iʿjāz, as he names his book as Nūr al-Īqān bi Iʿjāz al-Qurʾān, ‘Light of the faith through the inimitability of the Qurʾān.
Routing, having focal responsibility in MANET’s successful operation, are based on the assumption of nodes’ cooperation. However, this assumption exposes routing to various insider attackers. These attackers are the legal participants having privileged access to network when inducing attacks on routing. Furthermore, these insider attackers are either in the form of selfish nodes or malicious nodes. The motive of selfish node is saving its resources by not cooperating in routing activities whereas the purpose of malcious node is to attack the network. Therefore, providing security in routing against affirmed attackers has emerged a challenging issue in MANETs. In research community, trust management schemes are used to defend routing against insider attackers. The very focus of this research is to develop a trust management scheme for securing routing from insider attackers to launch blackhole and greyhole attacks. We proposed a trust management scheme, named as MT-SECURER (“Multi Factors Trust for Secure and Reliable Routing in MANETs”), for making routing secure against insider attackers (i.e., blackhole and greyhole attackers). This scheme develops trust from multiple factors, i.e., “node’s cooperation” from communication networks and “node’s relationship maturity” and “mutual friends” from social networks. Whereas for trust development, nodes’ personal observations along with neighbours’ recommendations are utilized. Neighbors’ recommendations, having a pivotal role in computation of trust, if hampered may entail in colossal attacks from dishonest trust recommenders such as “bad mouthing”, “ballot stuffing” and “random opinion”. Therefore, mitigation of dishonest trust recommendations has emerged as a stimulating research issue in trust management systems. In order to cater these challenges associated with dishonest trust recommendations, a technique named “intelligently Selection of Trust Recommendations based on Dissimilarity factor (iSTRD)” has been devised. iSTRD exploits observer node’s personal experience in conjunction with majority vote of the recommenders for removing dishonest trust recommendations. For performance analysis, MT-SECURER is used with AODV and DSR routing protocols and detail simulations are performed in order to examine the proposed scheme’s effectiveness in presence of blackhole and greyhole attackers and nodes’ mobility. The experimental results show significant improvement in “detection rate”, “packet delivery ratio”, throughput and “normalized routing load” with slightly increased “average end-to-end delay” when compared to contemporary schemes. Furthermore, iSTRD successfully removes the trust recommendations of “low trustworthyrecommenders” aswellasdishonesttrustrecommendationsof“highlytrustworthy recommenders”. Its efficacy is evident from enhanced accuracy of “recognition rate”, “false rejection” and “false acceptance”. Moreover, experiential results depict that iSTRD has unprecedented performance compared to contemporary techniques in presence of “bad mouthing”, “ballot stuffing” and “random opinion” attacks.
