حدود میں تخفیف کے مواقع

حدود میں تخفیف کے مواقع
مندرجہ ذیل چند اہم پہلوؤں کی نشان دہی کی جا رہی ہے، جن کی بناء پر حدود (عقوبات) میں معافی یا تخفیف کی گنجائش ملتی ہے:
1۔ اگر شریعت کا کوئی دوسرا اصول کسی خاص مجرم پر سزا کے نفاذ میں مانع ہو تو اسے سزا سے مستثنیٰ قرار دیا جائے گایا اس کے لیے متبادل سزا تجویز کی جائے گی ، جیسا کہ رسول اللہﷺ کے فیصلوں سے ثابت ہے۔ حضرت نعیم بن مسعود اشجعی  (م:36ھ)سے روایت ہے ، جب بنو حنیفہ کے مدعی نبوت مسیلمہ کے دو قاصد اس کا خط لے کر رسول اللہ ﷺ کی خدمت میں حاضر ہوئے تو آپ ﷺنے ان سے پوچھا کہ کیا وہ مسیلمہ کی نبوت پر ایما ن رکھتے ہیں ؟ انہوں نے اثبات میں جواب دیا تو رسول اللہ نے ارشاد فرمایا
" لو لا أن الرسل لا تقتل لضربت أعناقكما۔"49
" اگر قاصدوں کو قتل نہ کرنے کی روایت ہوتی تو میں تم دونوں کی گردن مار دیتا۔ "
اس کا مطلب یہ تھا کہ اگرچہ ارتداد کی وجہ سے وہ دونوں قاصد قتل کے مستحق ہو چکے تھے ، لیکن قاصدوں اور سفیروں کے احترام اور ان کی حفاظت کا ایک دوسرا اخلاقی اصول اس پر عمل کرنے میں مانع تھا اور آپ نے اسی کا لحاظ کرتے ہوئے انہیں بحفاظت واپس جانے دیا ۔ آپ ﷺنے اسی اصول پر یہ ہدایت کی کہ اگر باپ اپنے بیٹے کو قتل کردے تو اسے قصاص میں قتل نہ کیا جائے۔ حضرت سراقہ بن مالک  (م:24ھ)سے روایت ہے
" رسول الله ﷺ يقيد الأب من ابنه ولا يقيد الابن من أبيه۔"50
" رسول اللہﷺ باپ پر بیٹے کے قتل میں قصاص نہیں دلوایا کرتے تھے جب کہ بیٹے سے باپ کے قتل میں قصاص دلواتے تھے۔ "

اسلام اورہندومت میں احترام انسانیت ایک تقابلی جائزہ Respect for Humanity in Islam and Hinduism A Comparative Review

Every person in the world is respectable because he is a human being. All religions of the world have taught respect for humanity. It will not be wrong if we say that respect is the common heritage of humanity living in the world. Mutual respect is the secret and distinction of the development of nations. How many nations and cultures became enviable simply because they respected each other? In the present era, the dignity of humanity is being trampled everywhere. The murder market is hot everywhere. The standards of human respect are changing, sincerity, truth, human equality, and values ​​are being replaced by deceit, greed, envy, and selfishness. And it is done according to the resources. Man is the best of creation and legitimate respect and honor is his basic right. Therefore, no one can see his self-respect being undermined. That's why it has become very important to bring up topics like respect for humanity and explain the position and status of human beings in the light of religious books so that the respect and dignity of human beings are being trampled underfoot today, people should be made aware of the true status and status of human beings should be informed so that the importance of human blood can be estimated. An attempt will be made in this paper to present a comparative review regarding the respect and reverence that human has for Islam and Hinduism. Keywords: Respect for Humanity, Superior to all creatures, Religion, Islam, Hinduism, Respect, Self-respect

Optimal Parameter Selection for High Accuracy Area Classification in Hyper Spectral and Landsat-8 Imagery With Seasonal Change Detection

The thesis proposes area classification after construction of datasets with pre-processing for Hyperion Hyperspectral, Operational Land Imager (OLI) and Advanced Land Imager (ALI) orthoimages. The techniques perform comparative analysis of Hyperion Hyperspectral, OLI and ALI orthoimages in terms of high Signal to Noise (SNR), spectral band configuration, technical superiority, improved system design and high radiometric resolution. The thesis further proposes criteria for selection of parameters like gamma parameter, penalty parameter, pyramid parameter and classification probability threshold to achieve higher classification accuracies of Hyperion Hyperspectral, OLI and ALI Satellite orthoimages by using Support Vector Machine (SVM), Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) classifiers. After performing the comparison, the thesis selects SVM as the most appropriate classifier in terms of overall accuracy, individual classes and the best orthoimagery i.e. Hyperion, OLI and ALI respectively. The thesis also presents application of classification accuracy assessment on Hyperion Hyperspectral, OLI and ALI orthoimages by using different classifiers i.e. SVM, SAM and SID. The thesis also proposes high accuracy based seasonal change detection analysis technique on Hyperion Hyperspectral, ALI and different datasets of OLI by using change detection matrix and difference maps. As a result of these contributions, 1x Journal and 6 x Conference papers duly peer reviewed have been published. The pre-processing of 242 bands of hyperspectral data results in 136 calibrated bands. Quick Atmospheric Correction (QUAC) are applied to Hyperion Hyperspectral and Fast Line-of-sight Atmospheric Analysis of Hyper cubes (FLAASH) are applied to OLI and ALI imagery respectively for atmospheric correction. Principal Component Analysis (PCA) is used for dimensional reduction of the hyperspectral data. PCA reveals that 99.94% of the hyperspectral data are contained in the first 15 Principal Components (PCs). Distinct spectral profiles are identified for all classes which are highly beneficial for feature identification and classification of images. Novel parameters are selected for high accuracy area classification in hyperspectral, OLI and ALI imagery via SVM, SAM and SID classification techniques. High accuracy based post classification change detection analysis is used on Hyperion Hyperspectral, ALI and different OLI datasets to produce difference maps which provide information not only about change of category but also type of change i.e. “from-to” of category of classes. Change detection matrix is also used which shows an overall decrease and increase of corresponding spatial extension of classes whereas diagonal elements of the change detection matrix show the unchanged pixels for the individual classes. The post classification technique is selected because of its ability for accurate change detection analysis of imagery of different sensors and its advantages over pre-classification methods that it compensates for variation in atmospheric correction and in conditions where the change is limited due to small rate of change. The results show that Hyperion hyperspectral and Landsat-8 OLI data achieved higher accuracies in mapping applications and high accuracy based post classification seasonal change detection analysis on different datasets on OLI results extraction of accurate change detection information as compared to previous Landsat satellite series.
