حیرت ہے مے کدہ ہے کہ جنت خیال ہے

حیرت ہے، مے کدہ ہے کہ جنت خیال ہے
اک خوش نما سراب میں بھٹکا غزال ہے

دیکھے جو تجھ کو، دیکھ کے پھر ہوش میں رہے
باطل ہے اس کا دعویٰ، بڑا کج خیال ہے

قربت نے تیری بخش دیے فاصلے مزید
مجھ کو، مرے نصیب کو، سب کو ملال ہے

آنکھوں سے تم پکارو، ادھر وقت سے بھی تیز
میں دوڑتی نہ آئوں مری کیا مجال ہے

یاد اس کی ہے فضاؔ مری سانسوں میں دم بہ دم
رک جائے اک گھڑی بھی تو جینا محال ہے

Role of Tehrīk-E- Mujahedin in Promotion of Two Nation Theory: An Analysis of Freedom Movement in the Light of Islamic Teachings

It is a historical fact that wherever the Muslims went; they were considered as a distinct community from others due to their strong Islamic identity, which is called Two Nation Theory. Muslims, due to this Islamic Ideology, conquered Subcontinent and ruled over there more than one millennium. They successfully ruled the Indian Subcontinent till the Two Nation Theory was alive in their minds. When Mughal Emperor, Akbar tried to demolish this Theory by introducing his new, fake, fabricated and heretical religion, named as “Dīn-e-Akbari" or “Dīn-i-Ilāhī”. The renowned Islamic scholar Sheikh Mujaddid Alif Sānī challenged this so-called innovated religion. After that Shāh WalīUllāh Muḥaddith Dehlavī worked against this innovative and heretical religion. After it, the first organized movement was established by Shāh Abdul‘Azīz, the son of Shāh WalīUllāh in 1820 AD. This Movement played a dynamic role in Muslim's Renaissance in the Subcontinent. It also played a vital role to promote Two Nation Theory and major Muslim movements got inspiration from it. Although, this movement was crushed at Bālākōt in 1831 AD, but it left comprehensive impacts across the Muslim world, especially, in Indian Subcontinent. This movement kindled a flame of freedom in the Muslims of Subcontinent. Historically, this Movement has a practical participation in the Independence movement of Pakistan. As we see its role at the time of Referendum in the North-Western Frontier Province in 1947. It is an irrefutable historical fact that the leadership of Pakistan’s Movement, especially, Allāma Muhammad Iqbāl, was much influenced by Sayyīd Shahīd’s Movement. Therefore, this study presents a missing link between the Pakistan Freedom Movement and the Two Nation Theory. This study reflects historical and analytical approaches and its application frequently. In this study effort are made to explore the historical link between the Two Nation Theory and Tehrīk e Mujahedeen as well as its dynamic role during the period of Freedom Movement of Pakistan in Indian Subcontinent.

Preparation and Characterization of Bi-Based High – Tc Superconductors

BSCCO ceramic superconductors prepared by powder in tube, solid state reaction and melt quenching methods have been investigated. The aim is to determine the characteristics optimum doping concentration, quenching temperature and quenching medium for BSCCO ceramic superconductors. Studies were carried out on three systems (System I. Bi 1.7 Pb 0.3 Sr 2 Ca 2-x B x Cu 3 O y , System II. Bi 1.6 Pb 0.4 Sr 2 Ca 2 M 1 Cu 3 O y , System III. Bi 1.6 Pb 0.4 Sr 2 Ca 2 Cu 3 O y . In system I Ag- sheathed BSCCO tapes were prepared by PIT (powder in tube) technique. Samples were prepared by conventional solid state reaction followed by sintering at 850 o C. In system II, Melt quenching method was adopted to prepare BSCCO samples doped with Samarium and Terbium (M=Sm,Tb). In system III, BSCCO samples were prepared by melt quenching method. The synthesized precursors were quenched from 1200 o C, 1250 o C and 1300 o C to room temperature and sandwiched between brass, stainless steel, copper and bronze blocks. Critical temperatures of the samples were determined by resistivity temperature measurements using four probe technique at liquid nitrogen temperatures. Tc values for the samples were in the range (Tc onset ~ 99K – 104K). XRD analyses were done and lattice parameters of the samples were determined by indexing the diffraction peaks. Porosity of the samples was also measured. Surface of the samples was studied by scanning electron microscope (SEM) micrographs at a magnification of X1000. The SEM results indicate that 2223 phase may have been formed and the long grains of this phase might be obtained by quenching at this temperature. The atomic distribution ratio of each component element on the surface of the sample was investigated by energy dispersive spectroscopy (EDS). Bulk density of the samples was calculated by liquid immersion method. Density was found to be > 90% of the theoretical density of BSCCO glasses. The samples were thermo analytically analyzed by differential thermal analyses (DTA) and thermogravimetric Analysis (TGA). Activation energy, reaction rate constant and frequency factor for crystallization were evaluated employing different models. The sample quenched from 1250 o C on brass had the highest value of Tc (onset), highest volume fraction of 2223 phase, highest value of density and narrowest transition width. Multiphase structure of the samples was observed, major high-Tc 2223 phase coexists with small percentage of 2212 phase. Kinetic studies revealed that the thermal stability (ΔT = T x – T g ) increases for the sample quenched from 1250 o C. According to the results obtained it may be said that the structural, superconducting and thermoanalytical properties were optimum for the sample quenched on brass from 1250 o C.
