مواخات مدینہ

مواخات مدینہ
مکہ سے مسلمان مہاجرین ہر شے تج کر خالی ہاتھ مدینہ منورہ چلے آئے تھے۔لیکن ہر شے سے قیمتی اعلیٰ اور زندگی کا حاصل یعنی دین اسلام اپنے دامن میں سمیٹ لائے تھے۔ اس دولت بے پناہ کے ہوتے ہوئے انھیں کسی چیز کے چھوڑنے اور دوسروں کے قبضے میں چلے جانے کا دکھ تھا نہ غم۔ وہ اللہ کی اطاعت اور رسول کی پیروی میں سب وابستگیوں سے دور جا چکے تھے۔ بس رسول اللہ کا دامن مضبوطی سے تھامے ہوئے تھے۔
ان کے دامن سے ہو کے وابستہ
سب سے دامن چھڑا لیا ہم نے
بے سر وسامانی کے عالم میں آنحضرتؐ نے انصار و مہاجرین کے درمیان رشتہ اخوت قائم فرمایا۔ حضرت انسؓ کے مکان پر لوگوں کو جمع کر کے انصار سے فرمایا! یہ تمھارے بھائی ہیں ۔ پھر مہاجرین اور انصار میں سے ایک ایک شخص کو بلا کر آپؐ فرماتے گئے’’ یہ اور تم بھائی ہو‘‘۔ دو اجنبی بھائی بھائی بن گئے۔ ان میں سے چند کے نام حسب ذیل ہیں
۱۔ سید نا ابو بکر صدیق ؓ ، سید نا عمر فاروق ؓ
۲۔ سیدنا حمزہؓ کو سیدنا زید بن حارثہ ؓ
۳۔ سیدنا عثمان ؓ کو سید نا عبد الرحمن بن عوف
۴۔ سیدنا زبیر بن العوامؓ کو سیدنا عبداللہ بن مسعودؓ
۵۔ سیدنا عبیدہ بن الحارثؓ کو سیدنا بلال بن رباح
۶۔ سیدنا مصعب بن عمیر کو سیدنا سعد بن ابی وقاص
۷۔ سیدنا ابو عبیدہ بن الجراح کو سیدنا سالم مولا ابی حزیفہ
۸۔ سیدنا سعید بن زید کو سیدنا طلحہ بن عبیداللہ
۹۔سیدنا و مولانا محمد رسول ﷺکو سیدنا علی بن ابی طالب ۔ حضرت ابو بکرؓ کو خارجہ بن عرید، عمر کو عتبہ بن مالک اور زبیر کو سلمہ بن سلامہ کا بھائی بنایا۔

موقف الاصولیین من افعال النبیینﷺ

The Prophet (s. a. w.) was after all a human being with perfect human nature; whatever he did in his daily life represented human nature. All of his unanimously authentic doings have been classified by legal theorists into two major categories, the doings allowed to the Prophet (s. a. w.) alone with the exclusion of his followers and the doings that were meant to explain particular apparently ambiguous sayings. The latter category is further divided into two other categories: ( I) those acts of the Holy Prophet which explicitly refer to its explanatory nature, and (r) those acts whose explanatory nature is confirmed by other source. Islamic legal theorists have unanimity over the legal status of all categories of the Prophet’s (s. a. w.) acts. Certain acts of the Prophet (s. a. w.) are mandatoryfor him but non-mandatory for his followers; certain other acts are lawful for the Prophet (s. a. w.) but unlawful for believers; some acts are obligatory for the believers; and some acts of the Prophet (s. a. w.) are mere supererogatory. There are some acts of the Prophet (s. a. w.) on which legal theorists have not said anything concerning their legal status. The present paper represents an analysis of the views of legal theorists about the acts ofthe Prophet (s. a. w.) .

Analysis of Decoupled User Association in Multi-Tier 5G Heterogeneous Cellular Networks

High data rate demands of users have resulted into initiation of research on 5th Generation (5G) mobile networks. Up till now, Heterogeneous Networks (HetNets), Massive Multiple-Input Multiple Output (MIMO) and millimeter Wave (mmWave) technologies have been identified as key enabling technologies for emerging 5G networks. Out of these, HetNets along with efficient user association mechanisms are considered the most promising technology to achieve desired 5G objectives. At present, the cell association in existing HetNets is based on Downlink Reference Signal Received Power (DL RSRP) termed as coupled association which results into sub-optimal user performance, asymmetric load distributions and mobility management due to coverage areas asymmetries in HetNets. In order to improve existing HetNet user association, Downlink-Uplink Decoupling (DUDe) and biased cell association techniques have been proposed in literature. Out of these, the concept of DUDe has been recently introduced to address the shortcomings of coupled and biased cell user association. In DUDe, mobile may receive DL traffic from one BS based on DL RSRP and send UL traffic through another base-station (BS) based on the path loss. The DUDe can also be jointly used with dual connectivity to consume radio resources of at least two different network points for spectrum aggregation. Currently, some initial research on decoupled access has been undertaken but analysis in realistic scenarios is still an open research area. In the prior works, all network users are assumed to utilize decoupled access without considering its necessity and viability along with user location. Moreover, insights on the decoupling effects in terms of number of HetNet tiers and degree of HetNet densities has not been presented in the literature. The use of decoupled access with dual connectivity has also not been analyzed in multi-tier settings. In this research work, we propose a new and practical hybrid coupled / decoupled and Joint DUDe Dual Connectivity cell association schemes for K-tier HetNets which can be selected depending upon user location and by considering its benefits. Due to proposed scheme, one type of users can have UL-DL Coupled Association (CoA) with same BS despite the permissibility of decoupled association. Second type of users can follow UL-DL decoupled access called DUDe association policy. This type of user association in which users can have both coupled or decoupled access is called hybrid coupled / decoupled. In the thesis, analysis starts by examining the basic form of hybrid coupled / decoupled in two tier HetNets where UL and DL associations are based on path loss and DL received power respectively. Later on, the analysis is further extended for K-tier HetNets to generalize the analytical model. This analysis is followed by analytical modeling of Joint DUDe Dual Connectivity where user is allowed to aggregate channels based on Dual Connectivity along with Decoupled Access. With the use of stochastic geometry, we have developed closed form solutions for coverage, outage probabilities and average throughput by considering uplink power control, receiver noise and K-tiers of HetNets which is not available in the existing literature. The resultant performance metrics are also evaluated in terms of achieved gains over existing coupled access policies. Results show that cell association technique based on DUDe or Joint DUDe Dual Connectivity can significantly improve UL performance for forthcoming 5G HetNets in terms of coverage probability, outage probability and average throughput. Finally, the thesis is concluded by a summary of the findings and main outcomes from the conducted research along with suggested future directions.
