ہندی روزنامہ ’نوبھارت ٹائمس‘ کے چیف ایڈیٹر شری راجندر ماتھر ۱۱؍ اپریل ۱۹۹۱ء کوصرف ۴۵؍ سال کی عمر میں انتقال کرگئے ۔آنجہانی ماتھر بڑے ہی فراخ دل اورغیر متعصب انسان تھے ۔سیکولرزم کے دلدادہ اورمسلمانوں کے حقوق کے لیے ہمیشہ ہی جدوجہد کرتے رہتے تھے۔رمضان شریف کے عاشق تھے۔ روزہ افطار پارٹیوں میں باوجود بڑی مصروفیتوں کے ضرور جاتے تھے۔ اکثر کہاکرتے تھے کہ مجھے رمضان شریف کاانتظار رہتا ہے ۔کسی کوکیا معلوم تھاکہ اس نیک دل انسان کی موت رمضان شریف ہی میں ہوگی۔
ہندوستان میں مسلمانوں کاکوئی اخبار نہیں ہے جوان کے دکھ درد سب کو سنائے۔مسٹر ماتھر نے نوبھارت ٹائمس کے ذریعہ مسلمانوں کی مشکلات و پریشانیوں کواہلِ وطن تک پہنچایا۔ہر محاذ پر مسلمانوں کادفاع کیا۔مسلمانوں کوہندوستان کی ریڑھ کی ہڈی بتایا ۔فرقہ پرست ہندوؤں کوہمیشہ ہی انہوں نے ڈانٹا۔ واضح ہوکہ ہندی نوبھارت ہندوستان کاسب سے زیادہ کثیرالاشاعت اخبار ہے جس کے پڑھنے والے بھی کچھ ایک چھوڑ کرسب کے سب ہندو ہی ہیں۔ ایسے شریف اور نیک غیر مسلم انسان ومسلم دوست کی وفات سے یقینا مسلمانانِ ہندکو ناقابلِ تلافی نقصان پہنچا ہے۔ [اپریل ۱۹۹۱ء]
The position of poetry remained unchanged in Islam as it was before Islam, however with due some changes it was used as a weapon for the sake of Islam. This article will explain that how the poetry played a vital role in preaching of Islam. Islam absolutely encourages good wholesome poetry, which inspires one towards the fear of Allah, towards His awe and obedience, and towards anything that is good and made permissible by Allah and His Messenger (ﷺ). Following discussions are made in this article: Firstly Qur’anic views towards poetry; as the word poet came in Qur’an four times while the word poetry once. The total verses in which we see the word poetry are six. Secondly preaching of ethics through poetry; as we see that before Islam the Arab society was without any ethics, the Muslim poet called them for an exemplary life like of the Holy Prophet (ﷺ) Using of Qur’anic notion in poetry. Thirdly the Qur’anic notion was used largely in the beginning of Islam, especially by Ḥassān bin Thābit, ʻAbdullāh Bin Rawāḥah, Kaʻb Bin Zubayr and Nābighah Al Jaʻdī etc. Fourthly Answer to non-believers through poetry; as Ḥassān bin Thābit did through his poetry, and answer to the opposition, which impacts more sharp than sword and lastly using of Poetry during the war; it was considered as one of the biggest source for encouraging towards holly wars, the example of Haḍrat Khansā is most prominent. The research article basically focuses upon the importance of poetry in Islam, moreover how the weapon of poetry has been used by Islamic poets for defending Islam and how Islamic poetry vastly used for spreading of golden teachings of Islam.
Sampled-data output feedback regulation for continuous time varying system is discussed in this dissertation. The continuous time varying system is generally referred as plant. The plant output asymptotically tracks a continuous reference signal generated by an exogenous system. It is assumed that only the sampled-output of both plant and reference signals are available for measurement. The problem is to design a continuous-time (non-impulsive) reconstruction observer for both plant and exogenous system states estimation followed by a continuous-time controller to achieve ripple free smooth regulation. The design of reconstruction observer is based on two proposed observer schemes named mainly in accordance of their functionality that is current impulsive observer and prediction impulsive observer. This insight to the problem leads to an innovative idea of continuous (non-impulsive) reconstruction observer with the fusion of two impulsive observer designed under well-defined weighting function. A comprehensive convergence analysis of the proposed observer is presented for stable, unstable and highly unstable continuous-time linear time varying systems. The application of reconstruction (non-impulsive) observer for sampled data regulation without ripple is explored for linear time varying system. Augmented stability analysis is proposed for closed loop system. The overall scheme is iv demonstrated with the help of linear time varying system. Subsequently, single input single output feedback linearizable nonlinear system regulation is investigated in the frame work of suggested theory of non-impulsive observers. The proposed novel observer design not only provides state estimates but also performs feedback linearization for a nonlinear system. This ultimately leads to a non-impulsive continuous-time sampled-data regulation without ripples for a nonlinear system. A stability analysis is carried out while considering the model uncertainties of a nonlinear system as a non-vanishing perturbation. An example of a third order nonlinear system illustrates the efficacy of proposed design methodology.
