فصل ہذا کے مطالعہ سے یہ امر واضح ہو جاتا ہے کہ قرآن مجید فصاحت و بلا غت کے اعتبار سے بے مثل کتاب ہے۔ علم معانی، علمِ بیان اور علم بلاغت کے ماہرین نے اس کی لسانی و ادبی خصوصیات کو اپنی نگارشات کا موضوع بنایا ہے۔قرآن مجید کے اسالیبِ بیان اپنی اثر پذیری میں بے مثل ہیں۔التفات، تجانس ،تشابہ،تضاد، مغایرت، سجع، نظم اور استفہام اہم اسالیب شمار ہوتے ہیں۔اسلوبِ استفہام ، متعدد حِکم و فوائد کا حامل ہونے کے باوصف، ارسالِ دعوت کا منفرد اسلوب ہے۔ درحقیقیت سوالیہ انداز ، مخاطب کی توجہات کو پوری طرح مبذول کرنے اور حصولِ آمادگی کا اہم ذریعہ ہیں۔ قرآن مجید میں استفہام کسی حقیقیت کے اثبات اور نفی دونوں کیلئے استعمال کیا گیا ہے، اور غورو فکر پر آمادہ کیا گیا ہے۔تاکید واقرار ، ترغیب و عبرت پذیری،، تحقیر و توبیخ اور تعجب و نوازش کے مقاصد کے تحت اس کا استعمال ہوا ہے۔قرآن مجید میں آیات استفہام کا منفرد ادبی اسلوب موجود ہے۔
Today, majority of the Muslims' lives have turned out to be colored with a similar shade of the western civilization in every sphere of life. We watch that the matter of imitation achieved its most exceedingly awful pinnacle. In this era of ecstasy, the imitation of infidels and penitence of the Sunnah is growing rapidly due to the fact that Muslims have made it their habit. A particular group considers it enlightenment and ideological freedom and feels ashamed to follow Islam and Sunnah. The main reason for this attitude is that Muslims are unaware of the disadvantages of the imitation of infidels. In this article, the nuisances and flaws of imitation have been discussed, so that the Muslims could know about its imperfections and follow the Qur’ān and Sunnah.
Nitrogen glow discharge plasma is generated by number of power sources and has many applications in material processing such as Nitriding of different metal alloys. The material processing efficiency of the plasma may be enhanced by optimizing the related parameters of the discharge. The concentration of the active nitrogen species in the plasma may depend on various operating conditions such as input power of the discharge, pressure and gas flow rate etc. In order to improve the various excitation and ionization processes occurring in the plasma for the generation of active species, one way is to mix some inert gas in the nitrogen plasma. In the present study the diagnostics of Pulsed-dc generated nitrogen-methane-hydrogen mixture plasma is carried out to analyze the optimum working conditions for its application. Spectroscopic measurements of hydrogen Balmer-β and Balmer-γ line profiles are performed in an abnormal glow region of Pulsed-dc sustained nitrogen-hydrogen- methane plasma for investigating dependencies of their line shapes and intensities on discharge parameters. The excitation temperature Te is determined from Ar-I emission line intensities by using Boltzmann’s plot method of Balmer lines is found to be increased with methane mixing in nitrogen plasma. The electron density is extracted from Stark broadening (FWHM) of the Hβ emission profile. It is found that both the emission intensity and the broadening of the Balmer-β and Balmer-γ lines show significant dependence on the filling pressure in the same manner. However, both the emission intensity and broadening of Hβ line exhibit weak dependence on input power in contrast to the Hγ emission line. The concentration of active species N 2 (C 3 P u ) + + and N 2 ( B 2 S u ) are monitored in terms of the emission intensities of nitrogen bands of the second positive and the first negative systems respectively. The concentration of N 2 (C 3 P u ) active species is appreciably enhanced by methane mixing signifying the role of argon meta-stables in the excitation and dissociation processes. The effect of mixing of methane-hydrogen is studied on the surface nitriding os AISI-304 stainless steel substrate at temperature of 500 0C generated by 50 Hz pulsing source at powers of 300 and 500 watt and filling pressure of 1, 3, 5 mbar at different treated times 1, 2, 3, 4 and 5 hours. The samples are then analyzed for plasma induced changes in their surface properties by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and Vicker’s micro hardness testing. The XRD pattern confirms the formation of expanded austenite phase (γN) resulted by the incorporation of nitrogen as interstitial solid solution in the iron lattice. The EDX spectra show peaks corresponding to elements that are present in the surface of the substrate. It can be noticed that no additional peak corresponding to any impurity element, other than nitrogen, which is supposed to be present owing to nitrogen incorporation in the iron lattice is found in EDX spectra. The effect of ion etching is apparent from the SEM micrograph, which is normally expected during the nitriding process. All the nitrided samples show an increase in surface hardness as compared to that of untreated one. It is revealed that the surface hardness increase significantly with increasing nitriding time. Based upon optical measurement reported here, plasma discharge parameters can be optimized for the production of active species, excitation temperature Te and number density.
