جس رزق سے آتی ہو پرواز میں کوتاہی
نحمدہ وَ نُصَلِّیْ علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اساتذہ کرام اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پرلب کشائی کی سعادت حاصل ہورہی ہے وہ ہے:
’’جس رزق سے آتی ہو پرواز میں کوتاہی‘‘
جنابِ صدر!
انسان نے ایّام زیست گزارنے ہیں، عالم رنگ و بو میں سانس لینا ہے، اس جہاں کے اندر موجود نشیب و فراز سے اسے واسطہ پڑنا ہے، افراط و تفریط کا شکار بھی ہونا ہے، اور پھر افراط وتفریط کے گرداب سے اپنی ناؤ کی حفاظت بھی کرنی ہے، کا ئنات کی رنگینیاں، رعنائیاں اور دل آویز یاں بھی اُس کے لیے سازگار ماحول فراہم کریں گی۔ یہ سب منظر اس کی آنکھوں کے سامنے سے گزرنے ہیں۔
صدرِذی وقار!
ان انعامات الٰہیہ سے صرف وہی مستفید ہو سکتا ہے، جس میں ان کے حسین مناظر کو دیکھنے کی سکت ہو ،جس کی قوتِ سماعت مضبوط ہو، جس کے حواسِ خمسہ ان حسین و جمیل نظاروں کے لیے مستعد رہتے ہوں ،جونسیمِ صبح کی فرحت بخش ٹھنڈک محسوس کرنے کے لیے ہمہ وقت آرزومند ہو، جن کے جسم و جاں کسی اضمحلال کا شکار نہ ہوں۔
محترم صدر!
انسان کو اللہ تعالیٰ نے اشرف المخلوقات بنایا ہے، عظمت کا تاج اس کے سر پر سجایا ہے، انسان ہمیشہ اعلیٰ سے اعلیٰ اور ارفع سے ارفع کا آرزو مند رہتا ہے، اُس کا طائر غور و فکر بلند پروازی کا متمنی رہتا ہے، اُس کی اُمنگیں اور آرزوئیں عظیم سے عظیم تر ہوتی ہیں، وہ کبھی گھٹیا اور ادنیٰ حرکت کا مرتکب نہیں ہوتا۔ اُس کے حوصلے بلند اور عزائم مضبوط ہوتے ہیں۔
جنابِ صدر!

Imam Khattabi is considered as a glorious scholar of the fourth century. He has written several books in various scholarly traditions. One of them an important book is "Ghareeb ul Hadith". In this, he has not only interpreted the difficult words but also referred to as Ayaat, Ahadith and verses etc. Then, he also described the jurisprudential commandments existed in these Ayaat and Ahadith. Furthermore, in many places, hadith terms, legal maxims and wisdom of law are also part of this book. This book also holds a significant correlation with knowledge of Imam Khattabi's teachers because he mentioned the ahadith and sayings of scholars with his own chain. Due to these qualities of this book, not only did the scholars of language use it, but also magnificent mohaddiseen, jurists, explainers and researchers have also quoted it in their own books. Of course, it will not be unwise to say that like previous scholars and mohaddiseen this book is also important and need for today's scholars.
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.
