دکھاں دی پنڈ چائی جاواں
دکھی سجن بنائی جاواں
دکھ سمیٹاں جگ دے سارے
سکھاں نال وٹائی جاواں
دکھیاں نوں میں سینے لاکے
سکھاں سیر کرائی جاواں
ہر پاسے ای کیرے کر کے
پھلاں باغ لگائی جاواں
جنہاں روگ اولے لگے
اوہناں روگ ونڈائی جاواں
ونڈاں خوشیاں تے ودھ جاون
ونڈاں دکھ گھٹائی جاواں
Amongst other miracles of the Prophet Muhammad (PBUH), ISRAA and MAIRAAJ are one of the well-known miracles that have been discussed a lot in Sirat-ul-Nabi. This article, therefore, has brought under discussion the occur-rence of this miracle in the light of Qura’n and Ahadith in details. Furthermore, it has also been discussed whether the occurrence of this miracle was physical or spiritual in its nature. The concept of Sir Syed Ahmed Khan regarding this miracle has also been discussed; where he support his arguments with reference to some Ahadith, that the entire situation concerning the miracles was merely a dream and this miracle did not take place in physical form. According to him, this is against the law of nature. In this article the explicit concepts of Sir Syed Ahmed Khan have been rejected with the arguments given by the Majority of the Scholars and Muslim thinkers.
Membrane technology has been extensively explored as fascinating separation technique due to its energy efficient nature. This work concerns with the synthesis of five series of polymer membranes namely Polysulfone/Polyimide/Modified Zeolite mixed matrix membrane (MMM), Polysulfone/Polyimide/Silica nanocomposite membranes (NCM), Polysulfone/Polyimide-Silica- Modified Zeolite NCM, PIM-1/Modified Zeolite MMM and PIM-1/Modified zeolite thin-film composite membranes by solution casting method. Modified zeolite (MZ) filler was added to polymer matrix for tight packing of polymer layers. By adding silica (SiO2) and MZ filler to polymer matrix, the membranes exhibit properties of both organic and inorganic membranes. Polyimide and Polymer of intrinsic microporosity-1 (PIM-1) were synthesized by condensation reactions. Morphology and structure of fabricated samples were investigated by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD). Mechanical and thermal properties of nanocomposite membranes were also investigated. Polysulfone based membranes were investigated for antibacterial properties while PIM-1/Modified Zeolite MMMs were investigated for CO2/N2 separation. Thermal and mechanical properties of fabricated membranes were enhanced by filler addition due to fine compatibility and strong interaction of polymer and filler. Diffrential scanning calorimetry analysis (DSC) indicated increase in glass transition temperature (Tg) with increasing filler concentration. Better DSC specifications were evaluated for 10 wt% MZ content. Thermogravimetric analysis (TGA) complimented DSC results. Combining effects of Polysulfone (PSf), Polyimide (PI), SiO2 and MZ enhanced the antibacterial properties however, better antibacterial results were observed for 10 wt% nanocomposite in all cases. Integration of MZ filler in PIM-1 improved the CO2 permeability.Moreover, considerable increase in CO2 permeability was evaluated for alcohol treated PIM-1/MZ MMM as alcohol wash opens up the free volume.Effect of membrane’s thickness on gaseous flux was evaluated by fabrication of thin-film composite membrane (TFC) which improved the aging properties for TFC membranes as significant arrest was observed in permeability loss for TFC membranes. In all cases, CO2 permeability was observed to increase with increasing MZ concentration.Thus, we speculate that the permeation properties are adequately enhanced due to strong interaction and fine compatibility of MZ filler in PIM-1 matrix.
