ام المومنین حضرت زینب ؓ بنت جحش
نام زینب ؓ ، کنیت ام الحکم ، قبیلہ قریش کے خاندان اسد بن خزیمہ ہے ۔ان کاپہلا نام برہ تھا ۔ آپ ﷺ نے تبدیل فرما کر زینب رکھا ۔( مسلم شریف حدیث نمبر ۲۱۴۲)
آنحضرت ﷺ کے نکاح میں آنے سے قبل آپ ﷺ کے متبنیٰ بیٹے زید بن حارثہ کے عقد میں تھی ۔ وہ آنحضرت ﷺ کی پھوپھی زاد بہن تھی ۔اس وقت عرب معاشرہ میں دستور تھا کہ غلاموں سے مناکحت کو باعث ننگ و عار سمجھتے تھے ، یہی وجہ ہے کہ جب آنحضرت ﷺ نے سیدہ زینب ؓ کو اپنے غلام زید بن حارثہ ؓسے شادی کرنے کا پیغام دیا تو زینب ؓ اور ان کے بھائی عبداللہ بن جحش ؓ نے صاف انکار کردیا ۔ اس پر یہ آیت نازل ہوئی ۔’’ وماکان لمومن ولا مومنۃ اذاقضی ٰ اللہ و رسولہ امرا ان یکون لھم الخیرہ من امر ھم و من یعص اللہ و رسولہ فقد ضل ضلا لاََمبینا ‘‘۔ اس آیت میں مومن سے عبداللہ بن جحش ؓ اور مومنہ سے زینب ؓ مراد ہیں ۔ مطلب یہ ہے کہ کسی مومن اور مومنہ کے لیے یہ زیبا نہیں کہ جب اللہ اور اس کا رسول کوئی فیصلہ دے دے تو ان کو اپنے معاملہ میں کوئی اختیار رہے اور جس نے اللہ اور اس کے رسول کی نافرمانی کی بلا شبہ کھلی گمراہی میں مبتلا ہوا ۔اس لیے اس آیت کے نزول پر دونوں بہن بھائی راضی ہو گئے اور بحکم خدا وندی حضرت زینب ؓ کا نکاح حضرت زید ؓ سے ہو گیا ۔ شادی تو ہو گئی مگر لڑائی ہوتی رہتی جس سے زید ؓ آنحضرت ﷺ سے اس معاملہ کی شکایت کرتے اور عرض کرتے کہ میں زینب ؓ کو چھوڑ دیتا ہوں لیکن آپﷺ اسے...
This study aims to describe the concept of Islamic economics in poverty alleviation. This research method is descriptive qualitative research using data sources from literature or library research (library research). The research approach uses a normative approach and a historical approach. The normative approach is used to examine the ideals of the Islamic Economic conception and then analyze how it is applied. Meanwhile, the historical approach is used to study empirical facts about poverty alleviation. The results showed that the stagnant distribution will cause inequality and social inequality. For this reason, the implementation of the zakat obligation is a very urgent need. The priority of poverty alleviation according to the concept of Islamic economics is to overcome the causes of poverty, namely improving the distribution of wealth. Zakat is the main instrument which is a solution to these various problems, especially in dealing with poverty and social inequality. In Islam, the state must create programs and facilities that can overcome the problem of poverty, guarantee a decent life for the poor and provide the economic means needed to become a source of livelihood for the poor. Islamic economics can be explored more deeply for the development of economics and its benefits in alleviating poverty.
Multiple Input, Multiple Output (MIMO) antenna technology is being used extensively to meet the current wireless standards. It consists of multiple transmit and receive antennas to increase the signal capturing power and throughput. However, to achieve these goals, it is necessary to keep the coupling between antenna elements in an acceptable range so that multiple signals can effectively be resolved. In most of the existing MIMO antennas, separate antenna elements are used for occupying spatial diversity technique. In such a diversity scheme, isolation enhancement techniques may effectively be applied between these antenna elements. However, in spatial diversity, multiple antenna elements occupy more space to be accommodated in the devices with size constraints. Moreover, at higher frequencies, losses of metallic antennas become severe which significantly degrade the performance of the MIMO system. Recently, a possible alternative to these metallic antennas has been introduced in the form of dielectric resonator antennas (DRAs). DRAs offer potential advantage of high radiation efficiency and negligible conductor losses. DRA supports more than one resonant modes at different frequency bands, enable to meet the requirements of different applications with a unique device. Multimode excitation feature in the DRA makes it a suitable choice for use in multiband MIMO applications. However, more critical and challenging issue is coupling between modes excited in the single DR volume, especially when used for dual-band MIMO applications. This is the reason that dual-band MIMO DRAs are rarely found in literature. This thesis is composed of two single-band and four dual-band MIMO DRA designs. The first single-band MIMO DRA is excited by means of symmetric microstrip feeding and other DRA is excited by means of hybrid feeding mechanism. It is observed that hybrid feeding provides more isolation between antenna ports. This concept is extended to the dual-band MIMO DRA designs using similar and hybrid feeding mechanisms. The first dual-band MIMO design consists of symmetric microstrip slot feeding for pattern diversity at both WiMAX and wireless local area network (WLAN) bands. In the second design, compactness is achieved by stacking the DRA with high a permittivity material. Orthogonal modes at the two bands are xi excited in the DRA by coaxial probes and coupling between two ports is reduced by means of defected ground structure (DGS). Almost 80 % volume reduction has been achieved in this design by means of stacking approach. The last two designs presented in this work are based on hybrid feeding mechanism. Both of the dual-band MIMO DRAs have also been investigated for geometric scalability of the designs. As the resonant frequency of the DRA is inversely related to its dimensions, therefore, same design with different dimensions can be operated on other frequency bands as well. This property is termed as geometric or size scalability of the design. This re-sizing or scalability of the dual-band MIMO DRAs is a very interesting property and has not yet been investigated in literature. Frequency ratio is the ratio of higher band to the lower band which is an important parameter in the dual-band designs. Frequency ratio as a result of design scalability has also been presented in this work
