Phenomenon of entanglement was justly referred by Erwin Schrödinger as the characteristic trait of the quantum theory. On one hand, the phenomenon helped a lot to clarify the conceptual foundations of the theory. On the other hand, the very same nonlocal, counterintuitive correlations that bind entangled entities are now being employed as a backbone resource for most of the quantum informatics tasks including cryptography, teleportation, entanglement swapping, quantum computation and many others. Therefore controlled engineering of entangled states becomes vitally important. Present work deals with four theoretical proposals for the cavity QED based generation of a variety of entangled atomic and cavity field states including Bell, W, NOON, cluster and graph states. In first two proposals, atom interferometry in Bragg regime has been utilized for the engineering of Bell, W and NOON cavity field states. In this respect, basic constituents of Mach-Zehnder-Bragg (MZB) interferometers i.e. atomic de Broglie wave mirrors and beam splitters have been explored in detail. It is further demonstrated that by manipulating split atomic de Broglie wavepackets in a MZB interferometer, the required states can be engineered in an experimentally feasible manner while utilizing time-tested standard cavity QED tools. This work therefore opens up a new vista for quantum state engineering based on atom interferometry. Remaining two proposals aim at the generation of atomic and cavity field cluster and graph states and employ dispersive as well as resonant atom-field interactions as architectural components of the phase gate. First scheme in this section utilizes the concept of collective eraser whereas the second proposal, the most resource economical one, is based on the simultaneous resonant and dispersive interactions of two two-level atoms with an initially vacuum state high-Q cavity. Here the phase gate operation and hence the state engineering is accomplished when cavity is detected again into vacuum state after culmination of the interactions. Various parameters affecting success probability and fidelity of the proposed protocol have also been elucidated briefly. The parametric dependence of success probability and fidelity on most crucial factors of imprecision in the interaction times have also been plotted for the sake of quantitative assessment. This section is also concluded by providing a comprehensive note on the experimental feasibility of the presented work.

The account of the deeds and sayings of the prophet (ﷺ) has been carefully preserved since the dawn of Islam. This is what actually led Ernest Renan to believe that “[Islam] was born in the full light of history”, and that the life of Muḥammad (ﷺ) can be known as explicitly as that of any sixteenth century reformer. Notwithstanding, some contemporary writers doubt the historicity of Muḥammad (ﷺ) ; Robert Spencer is one of them. He is an American author. He is quite famous for his criticism of Islam and the prophet of Islam. He has published twelve books so far. He is a member of Melkite Greek Catholic Church. He contends that Muḥammad’s (ﷺ) historical value is in no way greater and more reliable than mythological figures or characters such as Robin Hood and Macbeth. He maintains that the very idea of subjecting the traditionally accepted account of the life of Muḥammad (ﷺ) and the origins of Islam will be regarded by many Muslims as an affront. To substantiate his argument, he rigorously criticizes the historical value of ḥadīth. He argues that aḥādīth were fabricated and compiled in the third century. He maintains that aḥādīth were concocted much later to be used as weapons in political strife and religious controversies. This paper is an academic attempt to prove that aḥādīth were painstakingly preserved and for that purpose various techniques were employed. Besides, it also sheds light on the reasons for the fabrication of aḥādīth and the ways and means utilized for sifting the genuine aḥādīth from forgeries. Findings of this article suggest that the minute details of the life of Muḥammad (ﷺ) have been scrupulously preserved; hence aḥādīth can be used as a reliable source of Sīrah.

TThhee mmaajjoorr oobbjjeeccttiivvee ooff tthhee ssttuuddyy iiss ttoo iidentify teachers’ pedagogical beliefs and practices in Teaching of English and their influence on students’ learning at secondary level in Khyber Pakhtunkhwa. The major objective is further strengthened by the research question and hypothesis: What beliefs do teachers hold and what classroom practices do they apply in teaching of English at secondary level? And there is no relationship between the beliefs and practices of English language teachers about teaching of English at secondary level in Khyber Pakhtunkhwa, respectively. Population of the study comprised all teachers and students (Male) at secondary level in Khyber Pakhtunkhwa, Pakistan. Khyber Pakhtunkhwa is geographically divided into three main regions: the Northern, the Central and the Southern. One district was selected from each region, and data was collected from 1200 students (male) and 120 teachers (male) in both Govt. and Private sectors, by employing multi-stage cluster stratified sampling technique. The tools used for data collection involved questionnaires, interviews, and observation checklist. The data was interpreted through both qualitative and quantitative techniques. The quantitative data was analyzed using Gamma coefficient correlation, and the qualitative data (interviews) were analyzed with the help of thematic analysis after transcribing and dividing the data under different themes and sub-themes. viii The results revealed that teachers of both sectors possessed strong beliefs about teaching of English along with language and its learning, basic language skills, grammar and its rules, students learning, curriculum of English, and students’ assessment of language learning. However, Govt. teachers’ beliefs were not reflected in their actual classroom practices, which resulted in students’ low understanding of English as a subject, and as a language. Contrarily, Private school teachers performed better in their classroom practices that are also reflected from Private school students’ language learning and its functional aspect. The teachers’ classroom practices were also compared with students’ views and their result displayed lack of coordination between teachers’ beliefs and their practices in Teaching of English. Govt. teachers were supposed to be highly skilled as compared to the Private school teachers because of the trainings, refreshers courses, seminars, and workshops offered to them by the governmental and non-governmental agencies; however, the results were contrary to the supposition. A sizeable number of English language teachers in Pakistan, especially in Khyber Pakhtunkhwa have a little awareness regarding their personal beliefs about teaching of English; therefore, this study provides the Govt. with an insight that how English language teachers’ view and value their professional beliefs to become effective teachers. It is; therefore, recommended that proper English language content-based training may be provided to the teachers with English language background and the present bulk of non-English language teachers may be replaced by English language teachers.
