منگ نہ میتھوں پیار او بیلی
اِسراں ہی ہن سار او بیلی
اوکھے ویلے نس جاندے نیں
ویکھو اج دے یار او بیلی
ساڈا بھارا کسے نہ چایا
بیلی اُنج ہزار او بیلی
اس بندے دے منہ نہ لگیں
جسدے یار ہزار او بیلی
اک پاسے تے موت کھڑی اے
اک پاسے نے یار او بیلی
کسے گھڑی وی چل سکدے نے
ایٹم دے ہتھیار او بیلی
Im?m Al Sh?f? Has great contribution towards grammatical and principled Arabic poetry. It is observed that his poetry is rich with ethical values. He gained his reputation at the same time as a Muslim jurist and a great man of wisdom. He is the writer of many books regarding Islamic jurisprudence, and a famous book of poetry “Deewan e Sh?f.” More over his books contain such ethical values in couplet mood. All of these discussed values, he truly abstracted and retrieved from the holy Quran and hadith. This article presents a special study regarding his valuable topics of ethics. The article is a comprehensive study of the ethical values found in the poetry of Al imam Al-Sh?f. The important ethical values of his poetry are: true advice of Muslim and knowledge positively. He also discussed some bad habits to aware the people about their bad impacts on nature and gives examples of their destructions in human beings. Some of them are fraud, cruelty and being the secretary of the ruler etc. He also discussed some bad habits to aware the people about their bad impacts on nature and gives examples of their destructions in human beings.

Entanglement, highlights all the counter-intuitive trait of the theory now employed for quantum information processing (QIP) tasks. However, entangled states are inherently fragile, prone to decoherence and decays through environmental interactions. Therefore the protection and preservation of entanglement becomes stringently important. The thesis describes the theoretical framework for the generation of various entangled states, their characterization and protection methodology involving both the discrete and continuous variables. First two proposals deal with engineering and protection of entanglement between quantum dots (QDs) placed in the vicinity of a nanoring having a surface plasmon (SP). Interaction of SP emanating from nanoring generates entanglement among the QDs and the counter propagating modes of SP. We also generalize it for multipartite case. QD interaction with SP is also utilized for protection of entanglement among QDs. The system with proven experimental feasibility open up a new vista for a sustainable entangled networks. Another way of protecting entanglement is to engineer environment. Here we consider an open system to be part of larger system-bath combination which is closed to the outside that is switching the system environment coupling from Markovian to non-Markovian. We investigate the dynamics and decoherence of entanglement in a system consisting of two atomic qubits trapped in two separate cavities containing structured reservoir in non-Markovian domain. Entanglement is quantified for various initial entangled states showing delay of sudden death of entanglement. For continuous variable regime, quantum beat laser (QBL) is considered. In order to preserve entanglement and to minimize entanglement degradation, structured environment is introduced by placing the system''s doubly resonant cavity into two mirrors forming another large leaky cavity. Here, the entanglement is plotted verses time for various values of driving field strength, purity and thermal noise. The results demonstrate that the employed preserving schematic not only enhances the entanglement among two modes of the lasers but it preserve the entanglement for longer time than in Markovian approximation for its efficient applications in quantum information processing tasks.
