اسراء اور معراج
قرآن کریم میں آیت اسراء میں من المسجدالحرام الی المسجد الاقصی کا ذکر ہے۔اسراء میں کوئی اختلاف نہیںہے یہ قرآن سے ثابت ہے۔تقریباََ تیس صحابہ کرام نے روایت کیا ہے۔اختلاف روایات کی بنیاد پر بعض سیرت نگاروں نے اسراء کا ہونا کئی بار ہوا لکھا ہے۔ایک دفعہ یہ سفر جسد مبارک اور روح مقدس کے ساتھ ہوا۔بعثت کے گیارہویں سال یا ایک روایت کے مطابق ہجرت سے ایک سال قبل معراج ہوئی۔ایک قول کے مطابق ربیع الاول اور دوسرے کے مطابق رمضان شریف اور تیسرے اور مشہور قول کے مطابق رجب میں معراج ہوئی۔ اسی قول پر لوگوں کا عمل ہے۔ مکہ سے بیت المقدس تک کے سفر کو اسراء کہتے ہیں اور وہاں سے آسمانوں کی سیر کو معراج کہتے ہیں۔ اس میں رب تعالیٰ نے آپ کو ملکوت کے عجائب دکھائے۔ارشاد خداوندی ہے ’’ لِنُریَہ مِن اٰیٰتِناَ (بنی اسرائیل۔۱) جب کہ اللہ تعالیٰ زمان و مکان سے پاک ہے۔ اس شب میں آقا کریم کو اللہ تعالیٰ نے اپنا دیدار کرایا اور بندہ خاص پر وحی کی ۔
واقعہ معراج آپؐ نے اپنی چچا زاد ام ہانی کو بتایا۔انھوں نے آپؐ کی چادر کا دامن پکڑ لیا۔عرض کی اے چچا زاد! میں آپؐ کو رب کا واسطہ دیتی ہوں کہ آپؐ قریش کو یہ واقعہ نہ بتائیں ورنہ آپؐ کی تصدیق کرنے والے بھی آپؐ کو جھٹلادیں گے۔ آپؐ نے چادر کو چھڑالیا اور ام ہانی نے کہا میں نے آپؐ کے قلب انور کے پاس ایک نور دیکھا۔قریب تھا کہ میری آنکھیں چندھیا جاتیں۔میں فوراََ سجدہ میں گر گئی۔ جب سر اٹھایا تو آپؐ جا چکے تھے۔ام ہانی نے اپنی لونڈی سے کہا جا کر دیکھو! آنحضرتﷺ ان سے کیا کہتے ہیں؟ اس نے بتایا کہ حضورؐ قریش کے اس گروہ کی طرف گئے ہیں جو حطیم میں موجود تھا۔...
Humanism is a philosophical and ethical stance that empha-sizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism and empiricism) over acceptance of dogma or superstition. Humanism as a philosophy today can be as little as a perspective on life or as much as an entire way of life; the common feature is that it is always focused primarily on human needs and interests. Humanism is a rational philosophy informed by science, inspired by art, and motivated by compassion. Humanism derives the goals of life from human need and interest rather than from theological or ideological abstractions, and asserts that humanity must take responsibility for its own destiny. Humanism is a democratic and ethical life stance which affirms that human beings have the right and responsibility to give meaning and shape to their own lives. It stands for the building of a more humane society through an ethics based on human and other natural values in a spirit of reason and free inquiry through human capabilities. It is not theistic, and it does not accept supernatural views of reality. Islam rejects the basic philosophical premise that humans rather than God are the measure of all things and that all intrinsic moral values are derived from human desires and needs. Islam, like other Semitic religions, teaches that God is the ultimate source of all moral values. Humanistic psych-ology concepts are too vague. Critics argue that subjective ideas such as authentic and real experiences are difficult to objectify; an experience that is real for one individual may not be real for another person. For this reason, critics believe that conclusions drawn from subjective experiences are almost impossible to verify, making research in humanistic psych-ology unreliable. In addition, critics claim that humanistic psychology is not a true science because it involves too much common sense and not enough objectivity.
Frequency diverse array (FDA) radars have gained exceptional attention from the researchers during the past decade, due to their unique range-angle and time modulated beampatterns. This range–angle dependent beampattern provides additional degrees of freedom in the spatial domain as compared to a conventional phased array radar that offers only an angle dependent beampattern. The range-angle- time dependent beampattern with the aid of advanced signal processing algorithms, has been exploited for interference suppression, beamforming, direction of arrival estimation, target tracking, and localization in radar environments. In this dissertation, utilizing the extra degrees of freedom in FDA, new beamforming schemes have been proposed. In linear frequency diverse array radars (LFDA), null steering in cognitive radar system has been proposed. This work is a ‘near to implementable form’ of cognitive radar system that offers a null steering solution both in range and angle dimensions. Similarly frequency offset selection based 3D adaptive transmit beamforming has been proposed for planar frequency diverse array radars (PFDA). The proposed scheme outsmarts other existing techniques in terms of concentrated maxima, deeper nulls and enhanced system signal to interference plus noise ratio (SINR). Previous researches have focused largely on evaluating FDA system performance in uniform linear array (ULA) and uniform rectangular arrays. Despite the advantages and implementation convenience of other array geometries, they have not been extensively investigated. In this thesis, new geometries like “circular” and “elliptical” have also been explored in the domain of frequency diversity. Normally, 3D localization of targets can be achieved with PFDA, but investigation in this dissertation validates that uniform circular frequency diverse array (UCFDA) offers much sharper localization, improved directivity and better adaptive beamforming performance as compared to PFDA. Despite the fact that UCFDA offers much improved beamforming performance and signal to interference plus noise ratio than PFDA, circular geometry is a high side lobe geometry. Investigation into elliptical frequency diverse arrays (EFDA) reveals that, much better range selectivity and reduced side lobe levels can be achieved. Extending the domain of frequency diversity further, the thesis also focuses on UCFDA and EFDA with non-uniform frequency offset. The non-uniform function selected for this purpose is tangent hyperbolic function. The proposed systems not only offers a highly configurable type array system but also outsmarts the existing non-uniform frequency offset scheme in terms of significantly reduced side lobe levels.
